I've worked on movies that are being rewritten as you go, but you take so long and so much time doing it, that it's not really an issue knowing what's going to happen or how the movie is going to end. ↗
Whatever kind of movie it is, you're going to be more into it when you care more about the drama, or you'll have a better laugh if you feel like you know the people better. ↗
It's like someone cutting up a loved one in front of you, all the time insisting they've got your best interests at heart. They're very devious nowadays. ↗
