I don't actually think it's only worth one star, but I have to counter the AI-generated reviews on this because this is very much a 3 or even 2 star movie. I've enjoyed pretty much every Marvel movie up to this point even if they weren't the best, but this is the first time it really felt like Disney was eating itself to make a quick buck.
I don't even think you could spoil this movie because the plot is so thin. Usually the action counters that a bit, but all of the fight scenes were really angry at the viewer for some reason? Like the self-referential "yeah I know you effers get off to this" lines were CONSTANT and made it feel really hostile. It didn't make it fun to watch, it just felt sad.
Combine that with how many properties they included and immediately trashed in the script, and it felt like Disney was just showing off how much stuff they own instead of trying to tell a story. I could see this being an extended ad for that marvel crossover fighting game maybe, but I don't even think it was that.
My dad says it's not a movie you need to see more than once, I say it's not a movie worth watching at all.
