The thing is, though, SVSG, I think of The Sixth Sense of a film along the same lines as The Usual Suspects. A commercial film with a twist. Nothing wrong with that, but there is a solution to the narrative, solvable upon rewatches if it isn't caught in the initial viewing. Lost Highway I like to think of as a filmic texture, pure Cinema. Cinema in the sense that it couldn't really translate to any other medium. The Sixth Sense could easily be told in novel form; Lynch's film, meanwhile, is a multi-layered cinematic poem, which does not hinge on one line, as you say, but begs to be experienced, not understood. Lynch's universe is one onto which my unconscious latches willingly; it's why I revisit his films, and why they get better and better each time...
