Definitely different strokes for different folks, but I cannot for the life of me understand how anyone can watch and rewatch 30+ movies which are completely interchangeable. Generic villain wants to do generic bad thing and generic hero saves the day in generic action sequences while making generic quips. Yawn. They are bad even as "low-effort movies" to relax.
Couldn't you describe a lot of movies as "antagonist does bad thing and protagonist stops them". What makes it generic? Why are they extra interchangeable in the super hero genre?
Yes, that would be obnoxious ... if that's what they said :)
To be clear, I don't like it either if others consider their taste to be 'superior', but simply stating what you prefer is not - I think - implying anything.
I feel like there's a trap people fall into where they tie some of their self-worth to their entertainment choices. If you don't like the music (say) that I do, then that seems like no big deal to me.
More generally, there is the opposite situation to being a 'superfan' where people delight in putting stuff down. Ultimately if you don't like (say) Marvel movies, then just don't watch them, of course. However it's reasonable to be critical of any entertainment or art form if you can articulate why and how they could be better.
I think one should try and watch some of the movies they are by default against. I did this with movies that end sadly and despite the overall greatness of the movie, I regret having watched them. But I did and now I know that this i snot for me. Same for horrors, thrillers and whatnot.
When looking for some new styles, I found it interesting to see some of them on youtube "recap" channels. This opened me to some new styles (to a point at least).
Same for music. I listen to more or less everything except a few styles which I do not like. Take rap for instance - most of the current rap music is unbearable to me and I can qualify why I feel that way (either from a music perspective, the lyrics or the overall message). This said, I like very much some of them, usually a bit older ones, or from people who has a message to send. It just takes an awful amount of time to track them down.
