Bosch: Start of Watch Premieres Jan. 10 on MGM+ With 8 Episodes: Who Plays Young Harry Bosch, Where to Watch, Whether You Need the Original First, and Why I Think a 1992 Rookie Is the Franchise’s Smartest Reset

Every long-running franchise eventually asks itself the same question: what if we went back to the beginning? On Thursday, Oct. 29, 2026, MGM+ answered it for Harry Bosch. The service released first-look photos of Bosch: Start of Watch, a prequel about the detective as a 26-year-old rookie in 1992 Los Angeles, and gave it a date. It lands Sunday, Jan. 10, 2027, with two episodes on opening night.

I like this idea more than I expected to, and I want to be upfront about both halves of that sentence: what has me hopeful, and what still makes me nervous. The facts come first, because that is what most people searching for this want: the schedule, the cast, where it streams, what it costs and whether the older shows are homework. My opinions come after, clearly labeled, so you can take the facts and leave the rest.

The case file in one glance

Everything in the case file comes from MGM+’s announcement and the series page for it, as reported by the outlets listed at the bottom.

Eight Sundays: the full release calendar

MGM+ gave three anchors: the Jan. 10 two-episode premiere, a weekly rhythm after that, and the Feb. 21 finale. The dates in between are my own count from those anchors, and the math holds, because two episodes on night one plus six weekly releases makes eight, and the sixth weekly release lands exactly on Feb. 21.

1. Jan. 10Episodes 1 and 2

   Premiere night, two episodes at once.

2. Jan. 17Episode 3
3. Jan. 24Episode 4
4. Jan. 31Episode 5
5. Feb. 7Episode 6
6. Feb. 14Episode 7
7. Feb. 21Episode 8, the finale

   Six weeks after the premiere.

A practical note, and it is just arithmetic: if you subscribe month to month on premiere night, your second billing date lands around Feb. 10, before the Feb. 21 finale. Whether that matters depends on how you like to watch. Some people will want the weekly ritual, and others will wait and finish all eight in a single billing month. Neither is wrong, but it is worth knowing before you click subscribe. Prime Video took the opposite approach with another big crime-and-action series this month, as I covered when The Terminal List Season 2 arrived with all eight episodes at once.

Where to watch it and what it costs

The short answer is MGM+. The announcement calls it an MGM+ series, and the list of markets is shorter than what the franchise had before: the U.S., the U.K., Belgium, Ireland, Italy, Germany, the Netherlands, Spain and Latin America. Reports did not name the Latin American countries, and some places you might expect, such as France, Canada and Australia, were not on the list in the coverage I read. If you live outside the listed markets, check MGM+’s own site for availability.

On price, PPC Land reports, citing Amazon, that MGM+ costs $7.99 a month or $61.99 a year in the United States, that it is ad-free, and that you can buy it on its own or add it as a channel inside Prime Video. Prices change, so confirm on the service before you pay. The older Bosch shows have streamed on Prime Video, and availability can vary by country.

Neither the announcement nor the series page explains why the prequel went to MGM+ rather than Prime Video’s main catalog. I am not going to guess at a reason, but here is what it means for viewers: the new show asks for a separate subscription or channel add-on from anyone who just wants to continue with the Bosch they already know.

Who is in it

Fourteen names are listed on the series page. Here is what MGM+ has said about the people at the top, and who else is in the cast.

• CM
  Cameron MonaghanHarry Bosch

  Known for Shameless and Gotham. He plays Bosch at 26, in his first days as an LAPD rookie.

• OH
  Omari HardwickEli Bridges

  Known for Power, Army of the Dead and Star Trek: Section 31. He plays the veteran officer, and MGM+ has not said more about the character.

• AG
  Ariana GuerraRosa

  Listed as a series regular. The announcement gives no surname or description.

• JP
  JD PardoCory

  Also in the eight-episode seriesCharacters not named

  Kathleen Wilhoite, William Fichtner, Rafi Gavron, Raphael Sbarge, Azita Ghanizada, Kenneth Miller, Seamus Dever, Ryan McPartlin, Marco Rodriguez and Shelli Boone.

Behind the camera, Tom Bernardo, who worked on Bosch and Bosch: Legacy, is the showrunner and co-created the series with Brian Anthony. Michael Connelly, who wrote the novels, is an executive producer. The series page also lists Stephen Kay and Sharat Raju as directors, though which episodes each directed has not been stated.

Do you need to watch Bosch first? My three ways in, ranked

No, you do not, and the people making the show say so. Bernardo has said the prequel is built so someone who has never watched Bosch can meet the character fresh, according to MovieWeb. That is good news, but it is not the whole answer, because there are really three different viewers asking this question. This is my own ranking of the ways in, from the one I would recommend most to the one I would recommend least for most people.

1. My pick
   1Start with Start of Watch
   Best ifYou have never seen Bosch, or you watched it years ago and the details are fuzzy.Why I like itThe story is chronological, it is designed as an entry point, and it costs you the least time. If you love it, the original series is still there afterward.The catchYou will miss the in-jokes and the sense of weight that comes from knowing where this young man ends up.
2. 2Watch the original Bosch first, then the prequel
   Best ifYou like to feel the full weight of a character before you see his beginning.Why I like itThe original ran seven seasons, from 2014 to 2021, with Titus Welliver as Bosch. Seeing the older detective first can make a rookie’s mistakes land harder.The catchSeven seasons is a real commitment, and there are only 73 days between the first-look announcement and the premiere.
3. 3The full release order: Bosch, Bosch: Legacy, Ballard, then Start of Watch
   Best ifYou are a completist who wants every piece of the franchise in the order it was made.Why I like itBosch: Legacy premiered May 6, 2022, and its final season arrived March 27, 2025, per Amazon. Ballard, a spinoff, released all 10 episodes of its first season on July 9, 2025, and Welliver plays the older Bosch in it opposite Maggie Q.The catchIt is the most viewing by far, and the prequel does not require any of it.

What MGM+ has said and what it hasn’t

A first-look announcement always leaves gaps. This is how I sorted what is actually on the record from what the material I read does not say.

Why 1992 matters

MGM+’s description paints Los Angeles in 1992 as a city on edge, with racial tension, gang violence and a fractured LAPD. That year has a specific weight. The Los Angeles riots began on April 29, 1992, after a jury acquitted four LAPD officers in the beating of Rodney King. The studio’s description talks about tension and unrest without naming those events, and it does not say whether the show depicts them.

Here is my read, and it is only that: a story about a rookie police officer in that city, at that time, with a plot about corruption inside the system, would be hard to tell honestly while pretending the moment did not exist. I cannot tell you the series does that, because nobody has said so. I can tell you it is the question I care about most, and it is the reason the setting excites me more than the heist does.

It also fits the character. Bosch’s motto is “Everybody counts or nobody counts,” and it only means something if the world around him is actively telling him otherwise. A rookie in a department at war with its own city is the perfect place to watch that belief get built.

My take: why a rookie is the smartest reset

Here is the opinion I promised. The original Bosch and Bosch: Legacy both followed a detective who already knew who he was. Start of Watch takes the one thing a long-running franchise rarely gets to do well, which is show the character before he became the character. Reports say no Connelly novel covers Bosch’s rookie years, which means there is no book to follow and nothing to be unfaithful to. I think that freedom is a gift. The writers get to invent his first mistakes, his first partner and his first moral compromises, and the audience gets to be surprised by a man whose ending we think we already know.

I also think pairing him with a veteran like Eli Bridges is the strongest signal in the announcement. Hardwick has spent years playing men who are charming and dangerous at the same time, and putting him on the other side of the law, as the cop who has seen it all, gives the rookie someone to learn from and someone to push against. A prequel built on that kind of partnership has a reliable engine, because every hour can be about two people disagreeing about what the job is for.

The real challenge is the recast. Welliver defined this character for years, and he is still playing the older Bosch on Ballard, according to MovieWeb, which also reports that he has publicly praised Monaghan. That is a generous handoff, and it matters, but it does not do the actor’s work for him. The test is simple: by the end of the second episode, I want to stop thinking about Welliver and start thinking about a different young man who could plausibly grow into him.

And then there is the platform. I understand the appeal of an ad-free service, and I do not pretend to know the business reasoning. But a franchise that once reached more than 240 countries and territories on Prime Video for its final Legacy season is now starting a new chapter in nine markets, behind its own subscription. That is a real cost to the audience that built the franchise. Amazon is also building its other crime franchise outward, with Neagley coming off the back of Reacher, as I wrote in my look at the Reacher franchise machine, so I am curious to see which strategy proves more durable.

My report card, graded before any footage

These grades are mine, not MGM+’s or anyone else’s. They are based on the announcement and the first-look photos only, which is why one of them is an incomplete.

• A-
  Premise

  A rookie year no one has shown, with a built-in mentor and a plot about corruption. Strong on paper, with the usual prequel risk of explaining too much.

• A
  Setting

  Los Angeles in 1992 is a character on its own, and the announcement describes it that way rather than as a backdrop.

• B+
  The partner pairing

  Hardwick as a veteran officer is the best casting signal so far, though MGM+ has said very little about Bridges.

• INC
  The lead recast

  I cannot grade Monaghan as Bosch without footage, and I would rather leave it incomplete than guess.

• C+
  How you get to see it

  Ad-free is nice. Nine markets and a separate subscription are a step back from what the franchise had before.

• A-
  Size and rollout

  Eight episodes, a two-episode premiere and a weekly run is a tidy shape that gives each episode room to land.

Overall, a cautious yes. The grades are opinion, based only on what has been announced, and they would mean something different with footage in hand.

Four signs it’s working

If you plan to watch the first two episodes, here is my own checklist for deciding whether the show has earned your next six Sundays.

1. Monaghan feels like a younger Bosch, not an impression.Look for the habits and the stubbornness, not the voice or the walk. A good prequel performance suggests the future without imitating it.
2. The city feels specific.Real neighborhoods, real tension and a department that feels fractured, not just a vague sense of “1990s Los Angeles.”
3. Bridges pushes back.If the veteran only exists to explain things to the rookie, the partnership is a missed opportunity. I want two people who disagree about the job.
4. The heist and the corruption plot start to move by the end of the premiere.Because the opening night is two episodes, there is room to establish the case early. A slow start would be a choice, not a necessity.
