Joel Schumacher was going to be my reply to this but I looked at his list and found several films of his that I actually liked. I just don't think he should have been allowed to touch the Batman series.
I feel like Vincent Gallo is probably the worst director around today. His films are incredibly self serviant and only serve to add to the ego that he has built around himself to tell him that he is an intellectual genius, when in reality he's just disturbed. Nothing interesting ever seems to come from putting myself through the tourture of watching his films.
By the way, I truely believe that Ed Wood was exactly what he set out to be. He peobably could have made better films but I think he realized his legacy would be longer and more interesting by going in the opposite direction and now look. We're still talking about him.
