It's true, Dave is totally vulgar and will try his best to insult you. So don't take the class if you are sensitive. But Dave is a brilliant story teller and he can teach you the secrets to successful storytelling. Even if you only take the class for his second lecture on story structure, it would be totally worth it. I actually clapped after the three hour lecture, it was that good. I thoroughly enjoyed this class. You will too if you are serious about learning how to write a successful screenplay.
