Though that’s hardly an argument against the idea of MCU movies always ending in a big fight as…
- The thing (or one of them) that sets Thor Ragnarok apart from the other MCU films is it consciously subverts the MCU big fight at the end trope. The fact its possible for a Marvel movie to stand out simply by veering very slightly from the “superhero fights villain, villain gets upper hand at first, but hero beats them in the end” model, says how ingrained it is in the MCU
- Just because it does things a bit differently it doesn’t mean that Thor Ragnarok doesn’t end in a big fight. Just like all the MCU examples you mention(that I’ve seen, and can remember the ending, at least) it absolutely gets resolved in a big fight.
