Unpopular opinion: I find all the super hero movies boring. They are all identical in plot, pacing, and formula, and so much of each movie is CGI that it's like watching a two hour video game cut scene. I also find them somewhat infantalizing. It's ok to like kid stuff, but it just seems these movies take themselves too seriously, as do their viewers. I think they would be better as animated films, like the 90s Spiderman or 90s X-men cartoons, but those already exist, so why redo them?
Another observation: they are no longer "comic book movies" since the movies are now the canon and the comic books follow them. I remember when people complained about some plot point or character detail that the movie got wrong compared to the comics. Now people don't even read comics, so the movie is automatically the new standard.
Also, Aliens (with an s) is one of the best action movies ever made, tied with The Terminator and Terminator 2.
