Ok, so I just watched Mulholland Drive and it was ok for the first hour or so. Then it just turned to "what the fuck? where? who?" I can't say I really understand what happened. Unless of course we just assume that it's all about Betty's the little girl in Hollywood fucked up head.
I think it has something to do with that exploding thong that her mother was wearing when she was pregnant with those puppies.
It's been so long since I've seen the movie that I'll have to rewatch it before I can post anything worthwhile. Once it's fresh in my mind, I'll check back in. But basically, I saw the first half of the movie as "Betty's" dying dream. There's other ways to look at it of course. Part of the fun of David Lynch movies is the wacked out interpretations you can make after watching the movie over and over again.
