Picture Purity

Here's a question that's been rolling around in my head for a while: how do you take your movie? I'm one of those people who likes their movie-watching experience in a very particular way.

1. I don't like people making a running commentary
2. I don't like it when people ask questions
3. I try to make sure that I can see a film in it's entirety in one sitting
4. I need to be in the proper mood for a film
5. Don't watch it with me if you're not interested (going on the computer, falling asleep)
6. Don't tell me about what's going to happen

However, I know some people who, for example, want to know the end at the beginning. Anyone have any interesting film-watching preferences? Or pet peeves?
