I think the wonderful thing about doing theater is that it's more of an actor's medium. I think that film is more of a director's medium. You can't edit something out on stage. It's there.
If you stick with a vision, it might not all work, but some of it will be absolute genius. To me, 15 minutes worth of absolute genius in a film is so much better than two hours of mediocrity. I would rather pay to see something different like that.
