My son wanted to go, so we did. It did suck. It's just hard to like the characters. They aren't well developed.
I wouldn't go see Superhero movies on my own either and didn't dig them when I was young. Never bought a comic book that I recall. However, I admit I enjoy most of the Ironman, Avenger and Xmen ones. Somehow they manage to convince me to suspend disbelief. The characters are pretty interesting even when they aren't shooting fireballs out of their palms. The only one of that group I disliked were Spiderman (all) and Guardians of the Galaxy.
