Non-Essential Intel
The permission slip. If you have been carrying guilt about not watching Eternals, set it down.
Every film on this list is a Marvel film. Most of them are fine. Some of them are good. A few of them are great. None of them are required to follow Avengers: Doomsday, and many of them are not strong enough to recommend on their own merits.
The early MCU was figuring itself out. These films exist because Marvel had not yet learned what it was building. They mostly do not feed Doomsday, and the parts of them that matter for later films get re-explained in the sequels.
Skip it. This is the only MCU film starring Edward Norton, and Marvel has spent every film since trying to act like it did not happen. Bruce Banner's origin gets covered in dialogue in The Avengers. You lose nothing.
Skip it. The film exists to introduce Black Widow and War Machine and to set up The Avengers. You will meet both characters in better films. Whiplash is one of the weakest MCU villains. Tony's arc here is "deal with the same emotional issues as Iron Man 1 again, with a new prop."
Skip it. Thor's character development here gets undone by Thor: Ragnarok in a deliberate, much better way. The Earth scenes feel like a Hallmark movie with a hammer. The Asgard scenes look small in a way Ragnarok will later make look ridiculous. If you want Thor's story, start with Ragnarok.
These are sequels to films you may have already watched. They are usually weaker than the originals and do not advance any thread Doomsday cares about.
Skip it, unless you specifically want to see Tony deal with PTSD after The Avengers. Shane Black's instincts as a director are interesting, but the Mandarin twist is one of the most divisive choices Marvel has ever made, and the film overall feels like it is fighting the genre it is supposed to be in. Tony's arc gets resolved better in Endgame.
Skip it. Most Marvel fans agree this is the weakest MCU film. Malekith is a villain with no presence. The plot exists to move an Infinity Stone from point A to point B. Ragnarok specifically jokes about how forgettable this film is.
Skip it, with one caveat. Ultron is a fun villain and James Spader is great. But the film tries to do too much (introduce Vision, Scarlet Witch, Quicksilver, expand the team, set up Civil War, and resolve a global threat) and ends up doing most of it half-well. Vision and Wanda matter later, but you can pick them up in their own shows or in Civil War without losing the thread.
Skip it. This was supposed to launch Kang as the next big bad. Then Jonathan Majors was fired, Marvel scrapped the Kang storyline, and this film essentially became a dead end. The film itself is also not strong. The Quantum Realm visuals are creative; everything else struggles.
These are films I genuinely like, or that have a real fan base. They are skippable not because they are bad, but because Doomsday does not need them. Save them for after.
A charming heist film. Paul Rudd is great. The shrinking gimmick works better here than in any sequel. But Scott Lang's larger MCU role comes from Endgame, not from this film. You can pick him up in Civil War.
Same situation. Lighter than the first, fine on its own. The post-credits scene matters slightly for Endgame but not enough to require the whole film.
This one hurts to cut. Shang-Chi is a genuinely good film. The fight choreography is the best the MCU has done. The cast is excellent. Simu Liu is going to be a major part of the next phase. But Doomsday does not actually depend on Shang-Chi's events, and the film is not connected to the multiverse threads we need. Watch it after Doomsday if you have not already.
Chloe Zhao made a beautiful, slow, contemplative film that was sold as a superhero blockbuster. The result divided everyone. The film has some of the best visuals in the MCU. It also moves at a pace that frustrates most viewers. The events do not affect Doomsday in any visible way. Skip unless you specifically want the experience.
Doomsday is technically a sequel to a few recent films that came out in the last two years. Most of them do not actually carry critical information forward.
Sam Wilson's first solo film as Cap. The premiere did not generate the buzz Marvel hoped for. The film deals with Sam's identity as Captain America and the political fallout of inheriting the shield. None of it strictly feeds Doomsday. Skip if time-crunched.
This one is worth a note. It was better received than most recent Marvel releases. The team of misfits and antiheroes that forms here will likely play a role in the broader Marvel future, but Doomsday does not require them. If you have time and want a non-required watch that is also genuinely fun, add this one. Otherwise, skip.
Already covered in Extra Credit. It is a sequel to Captain Marvel and technically a Doomsday feeder, but the connection is thin enough to skip.
Most of the Disney+ shows are skippable for Doomsday prep. The exception is Loki Season 2, which is on the Spine because the multiverse rules matter.
Quick takes on the rest:
- WandaVision (2021): Beautiful, ambitious, sets up Wanda for Multiverse of Madness. You can skip and get the necessary context in Multiverse of Madness.
- The Falcon and the Winter Soldier (2021): Sets up Sam Wilson as Captain America and Bucky's continued arc. You can pick both up in Brave New World or just from context.
- Hawkeye (2021): Introduces Kate Bishop. Not Doomsday-relevant.
- Moon Knight (2022): Excellent show, completely disconnected from the larger MCU so far.
- Ms. Marvel (2022): Introduces Kamala Khan, who appears in The Marvels. Not Doomsday-relevant.
- She-Hulk: Attorney at Law (2022): Comedy. Fun. Not Doomsday-relevant.
- Secret Invasion (2023): Skip. Widely considered the weakest MCU show. The Nick Fury moments matter slightly, but not enough.
- Loki Season 1 (2021): Technically you can skip and just watch Season 2, but Season 1 sets up Sylvie and the TVA. If you have time, watch it.
There are a few films I have not listed because they are in either the Spine or Extra Credit. Captain Marvel, Captain America, Iron Man, the Avengers films, the Guardians films, the Black Panther films, Doctor Strange, Spider-Man, Thor: Ragnarok, Loki Season 2, Multiverse of Madness, Deadpool & Wolverine, Fantastic Four First Steps, and Wakanda Forever are all required or recommended.
If a film is not on the Spine, not in Extra Credit, and not on this list, then either it has not been released yet, or it was a TV special I did not have a strong opinion about. You are not missing anything.
If you skip everything on this list, you are watching about 13 to 19 films (the Spine, plus whatever Extra Credit calls to you) over six months. That is a reasonable, sustainable pace. You will walk into the theater in December prepared, without burning out.
The cut films will still be there after Doomsday. If you fall in love with this universe through the Spine and the Extra Credit, you will know where to go next.
Cutting Shang-Chi hurt. It's one of the best-made films in the entire MCU, and the fight choreography is the kind of thing you watch a second time just to study the craft. And here it sits on the skippables list, because Doomsday doesn't need it. That's the honest tension of writing a guide like this.
The "do you need it for the plot" filter isn't the same as the "is it actually good" filter, and I tried to be clear when those two disagreed. The worst version of this guide would have just listed what's required without acknowledging what we lose by skipping the rest. So consider this my permission slip to come back for the good stuff after Doomsday.
If you find yourself with extra time once you've finished the Spine, this is the list to mine. There are real gems here, just not the ones you need before December 18.
