i saw mulholland dr after it came out, when people were hyping it up a lot, so maybe thats why i didnt think that much of it. its not as filmic looking or as dark as his other movies (prob cos it was meant for tv - shame it never got commissioned, it could have been really good) and for some reason, i think its a bit gimmicky, the way it suddenly moves the timeline around in the second half. makes me think he was a bit tarantino influenced. actually i think that about lost highway too, eg all the stuff with mobsters. reminds me a bit of ghost dog too. might have to watch them again though, i have to be in a certain mood for lynch i find.
yeah, always seemed like an attempt at a refinement of lost highway, although I might eventually prefer LH. I would say MD is still pretty fucking dark though, even if not quite as much so as Fire Walk With Me. The scene where she's being picked up from the airport is chilling, for example - straight out of Rosemary's Baby. almost.
And the scene with Naomi Watts' audition is worth the price of admission in itself.
