I'll go first. Mine is that I can't stand the Deadpool movies. They are self aware and self referential to an obnoxious degree. It's like being continually reminded that I am in a movie. I swear the success of that movie has directly lead to every blockbuster having to have a joke every 30 seconds
I think the problem with Sucker Punch was no one really knew what it was about before watching it and ended up being like "this is fucking weird". If you look at everything as though it's from inside the mind of someone who was just lobotomized then it's pretty good, imo.
