Many filmmakers have interrogated the dream factory that employs them, but only David Lynch understands that to capture its insidious beauty requires rendering it a dream itself, in all of its prismatic glory. While “Mulholland Dr.” is — and is about — a dream, it feels like a disservice to the film to describe in such elemental terms.

it’s eminently possible to pull apart the surrealism in Lynch’s masterpiece to determine “how it works,” but doing so can’t ruin or even explain the film’s magic, which lies in how Lynch organizes every element at his disposal until real and unreal become indistinguishable.

their journey from A to B animates the desperate mystery at the film’s core, which revolves around personal identity and encompasses a web of taciturn mobsters, dopey hitmen, soothsaying cowboys, and ambitious filmmakers cut down at the knees.

Watts’ disarming portrayal of a wide-eyed naif evaporates the instant Betty enters a crucial audition; when it’s over, Watts and her character(s) suddenly feel unknowable and out of reach, just like movie stars.

the ugliness of the factory’s gears become readily apparent, and “Mulholland Dr.” becomes about the despair and heartbreak that comprise Hollywood’s background.

Time and again, Yang’s characters return to the feeling that something isn’t enough. A child’s presence isn’t seen as enough comfort to his comatose grandma if he can’t think of something eloquent to say. The effort spent on a massive video game project at work inevitably means not spending enough time with family (and vice versa). And the makeshift pile of memories and bonds that we acquire over the course of a lifetime — always doing our best — never feels like enough when we compare it against our Platonic fantasies of what could have been.

The finished film feels like a parting gift from an artist — already at the end of his tragically short life — who came to appreciate that a well-lived human life contains more poetry than all of the planet’s art put together.

David is unique because the love he carries for Monica quite literally allows his mommy to be real again, and in doing so it sees him become the only son humanity has left. The super robots designate him as an original because he actually knew a living person — he’s the realest boy in the whole wide world. And so the artifice of their experiment gives way to the most genuine of truths:  Love doesn’t exist in defiance of time — love is the defiance of time. And like David, the movie that Spielberg has made about him will never age a day.
