Mulholland Drive
Certainly strange; but very fascinating and quite immersive. I have to be up early in the morning so can't give a massive review, but I personally think I have a relatively good understanding of what happened, contrary to the reports of some that it is impenetrably nonsensical (though certain parts make no sense to me at this moment).
Also, Naomi Watts is hot.
Overall, I'm glad I've seen it.
