Hmm, almost every story type has been done to cliche. Having a superhero flavor makes no difference, at least to me. I don't know much about the hero so I don't have much interest in this instance.

I'd love a second Batman movie, or a good Green Lantern one etc. Couldn't care less for this one

I don't think so, I just think these movies have largely not been very good. Like, I really liked Loki S2, have rewatched NWH a hundred times, I liked the Marvels, etc. The problem isn't superheroes, you can use that as a backdrop for just about any type of story you want to tell and it can be great. For example, WandaVision tells a very different kind of story than anything else and it was really good. But of course, Marvel decides (I'm guessing late into post-production) they're going to fuck up all of that character development in a post-credits scene and then ignore it entirely in the next movie.

I think they're going to have to get a lot more creative about what types of stories they want to tell and what themes they want to get after and stop making them feel like cookie cutter properties. The early phases I think managed this a little better. Like, I remember walking out of TWS and thinking "damn, that was a really good Bond film with a Captain America skin on it" which is a compliment. Somewhere in there the whole thing got really generic.
