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
The Exorcist (original) is one of the most boring horror movies I’ve ever personally sat through and I have no earthly idea why it caused such a stir at the time. Whole movie is a snooze fest until the last bit, but I found it less scary and more humorous.
