Make a movie about each X man where nothing happens except they don’t like each other. Then make a collaboration movie where they have to team up and fight a massive evil guy together unwillingly at first. The movie will have hundreds of plot holes but they’ll just add time travel to make up some random bullshit. By the end of the movie they’ll beat the unbeatable bad guy and be friends again.
TLDR -You’ll give them your money and they’ll give you shit movies.
