These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Mulholland Drive
Awesome Music: This is scored by Angelo Badalamenti, who's no stranger to Lynch, and he doesn't disappoint. Even if you hate the movie, you have to admit that the soundtrack's pretty good.
Big Lipped Alligator Moment: Even in a film as random as this, the man behind Winkie's scene stands out as pretty unrelated to everything else.
Jerkass Woobie: Diane. She's pretty pitiful, even after having her best friend/lover killed out of jealousy.
The director In the first half as well, who gets an over-the-top Trauma Conga Line thrown his way from the word "go".
The film was considered so incomprehensible by the studio that they made Lynch include a set of clues to the plot in the initial DVD release. Unfortunately, they made Lynch write the clues — and he wrote them in such a way as to heap even more fuel on the fire of Wild Mass Guessing.
