I have a different take...

Rating: Null/10 (13 May 2002)

**POSSIBLE SPOILER(S)**
This film was Lynch all the way. Spooky and strange. However I enjoyed the viewing. Obviously out of chronological order much like a Tarantino film. Many have stated the plot to be part dream/nightmare, part reality. I believe the first half of the movie takes place after both women are dead. (One suicide, one murdered.) Diane's afterlife - where they meet as ideal lovers. One of them with amnesia the other a wholesome girl next door type. Adding to the ideal for Diane is her success in being cast on the big screen (as Betty). Which was her dream in life. The second half of the film depicts events leading up to that point - Camilla dumps Diane, Diane in her rage hires a hit-man to kill Camilla etc.
Can't say I'm much of a David Lynch fan. Not a bad film though.
