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
E.T. is decent at best. I wanted to watch it as a young kid, but wasn't allowed. By the time I finally watched it, I found it fell short of my expectations and I found it quite dull. Super 8 was also a middling film, but I thought it was slightly better than E.T.
