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
If you didn’t love the first one, I doubt you’ll like the others. I haven’t read all of them yet, but everyone I know who has read them all always started by enjoying the world of the first one first.
