When I was younger, I enjoyed superhero movies for the most part. Every now and then I watched a superhero movie like The Dark Knight and the Sam Raimi Spiderman trilogy, but I was never that into it. It was the early 2010's when the superhero craze began, with marvel's "cinematic universe" and at the time, I thought it was a really cool concept.
But at some point I began to lose interest. One of the big problems was that Marvel movies started to feel less like decent stand-alone movies and more advertisments for other movies. Many of those movies (especially Marvel) seemed to exist solely to set up a future movie in the series. At this point there were so many of these movies coming out, and they kept following the same formula and hardly tried experimenting with anything. As a result most of these movies got way too predictable and same-y.
There were a few newer superhero movies that I did enjoy, such as Spider-man: Into the Spider-verse, Guardians of the Galaxy, and Avengers: Infinity War. Into the Spider-verse was probably the best movie to come out of this new wave of superhero movies. It's so fun, creative and stylized to the point where it makes every other newer superhero movie look dull in comparison. Guardians of the Galaxy isn't on the same level as Spider-verse but I do enjoy it more than most other Marvel movies just because it had more personality to it, which is something a lot of Marvel movies lack. Avengers: Infinity War was the big payoff for nearly 10 years of Marvel movies, and the hype for this movie was really huge. Maybe not as big as Avengers: Endgame, but I preferred this as a movie. Honestly I would have been satisfied if the MCU just ended at Infinity War.
A thing I find annoying about Marvel in particular is most of it's humour. Most attempts at making a joke are just overused quips and one-liners like "wow, didn't see that coming" or "uh, that sounded better in my head". There's nothing wrong with a movie being silly or light-hearted, but something about the way Marvel does it bugs me. It would be nice if Marvel made more movies that had different tones and tried out different ways of telling their stories, but that might not make as much money, so that's not going to happen.
I haven't watched a new superhero movie since Avengers: Endgame, but I did rewatch The Dark Knight recently and it reminded me of how good superhero movies could be.
