This is an extraordinary movie experience, and David may have out-Lynch-ed himself with this one. It is quite surreal and, contrary to Mulholland Drive which can be "explained" - I do not think there is a tidy plot you can unravel 100 %. It is like some mathematical surfaces that you cannot quite put flat on a plane: works 90 % but some wrinkles remain. No matter: the sound, images, atmosphere, music, characters, and story line all make this fantastic. I don't know how to describe this, you have to see this.
This is really a DVD worth having because you can watch it many times and still be amazed. BRILLIANT.
