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 it was also challenging to write a story that can work both forwards and backwards. I don’t think they succeeded in doing so but I’m impressed that they tried.
