Yeah, same here. I realized a small while ago that I might be completely burnt out on superheroes. The last Marvel movie I saw was Doctor Strange, and only because I was bored and surfing...certain websites. I'll probably see Infinity War because I don't want my near decade of watching Marvel movies to go to waste, but none of the trailers I've seen for it have made me feel anything.
I just hope they don't skimp out on character deaths.
EDIT: Actually, I forgot that I saw Homecoming. I remember liking that.
