Avengers: Doomsday hits theaters December 18, and the discourse has already started eating itself. Half the internet thinks this is the movie that gets the MCU back on track. The other half thinks Marvel is just rearranging deck chairs with a bigger cast list. Both things can't be true, but that's never stopped a good tier list argument.
We just put together MCU Movies Ranked: Every Marvel Film From Best to Worst, running all the way from the first Iron Man to whatever Marvel dropped last month. Doomsday isn't on it yet, because it isn't out yet. But that hasn't stopped fans from mentally slotting it in before a single ticket sells. So let's talk about where it's actually likely to land, and why the range of outcomes here is wider than almost any Marvel movie in years.
The case for S-tier
The pitch for Doomsday is basically "remember how good Endgame felt?" A massive ensemble cast, a villain built up across multiple projects, and the sense that the MCU is finally paying off threads instead of just planting new ones. If the movie sticks the landing the way Endgame did, it could genuinely crack the top of our rankings next to the first two Avengers team-ups and Infinity War.
The ingredients are there. Big crossover event movies tend to overperform expectations when Marvel actually commits to consequences instead of resetting everything by the credits. If Doomsday kills off characters, closes arcs, and doesn't chicken out with a mid-credits "just kidding," that's the kind of thing that ages well on a tier list.
The case for it sinking like a stone
Here's the other side. The post-Endgame era has been rough. Too many Marvel movies in the last few years landed somewhere between forgettable and actively frustrating, and a chunk of the fanbase has checked out entirely. Throwing a huge cast at a movie doesn't automatically make it good, it can just as easily make it feel cluttered and rushed, with nobody getting a real arc because there are twelve people who need a moment.
There's also the villain problem. Big bad guys in crossover movies live or die by whether they feel like a real threat or just a CGI punching bag with a cool entrance. If Doomsday's antagonist doesn't land, no amount of returning cameos will save it from middle-of-the-pack purgatory, or worse.
