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 wouldn’t agree that Marvel films have a competent plot, but maybe that’s because I generally struggle to follow the plot through all the other crap, and am left wondering “was that a plot hole or did I space out during all the explosions and miss a critical line of dialogue?”
They’ve been using the same plot outline for the whole series so they surely have it sorted by now.
