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 don’t think it’s OPs point that the movie did it first, just that it was annoying in the movie. And they’re right.
The whole point of Deadpool is the self awareness though. You can find it annoying, it’s not for everyone, but it’s true to what the character has become.
