The fact is that David Lynch treats the subject of evil better than just about anybody else making movies today—better and also differently. His movies aren’t anti-moral, but they are definitely anti-formulaic. Evil-ridden though his filmic world is, please notice that responsibility for evil never in his films devolves easily onto greedy corporations or corrupt politicians or faceless serial kooks. Lynch is not interested in the devolution of responsibility, and he’s not interested in moral judgments of characters. Rather, he’s interested in the psychic spaces in which people are capable of evil. He is interested in Darkness. And Darkness, in David Lynch’s movies, always wears more than one face. Recall, for example, how Blue Velvet’s Frank Booth is both Frank Booth and “the Well-Dressed Man.” How Eraserhead's whole postapocalyptic world of demonic conceptions and teratoid offspring and summary decapitations is evil… yet how it’s “poor” Henry Spencer who ends up a baby-killer. How in both TV’s Twin Peaks and cinema’s Fire Walk with Me, “Bob” is also Leland Palmer, how they are, “spiritually,” both two and one. The Elephant Man’s sideshow barker is evil in his exploitation of Merrick, but so too is good old kindly Dr. Treeves—and Lynch very carefully has Treeves admit this aloud. And if Wild at Heart’s coherence suffered because its myriad villains seemed fuzzy and interchangeable, it was because they were all basically the same thing, i.e. they were all in the service of the same force or spirit. Characters are not themselves evil in Lynch movies—evil wears them. This point is worth emphasizing. Lynch’s movies are not about monsters (i.e. people whose intrinsic natures are evil) but about hauntings, about evil as environment, possibility, force. This helps explain Lynch’s constant deployment of noirish lighting and eerie sound-carpets and grotesque figurants: in his movies’ world, a kind of ambient spiritual antimatter hangs just overhead. It also explains why Lynch’s villains seem not merely wicked or sick but ecstatic, transported: they are, literally, possessed. Think here of Dennis Hopper’s exultant “I’LL FUCK ANYTHING THAT MOVES” in Blue Velvet, or of the incredible scene in Wild at Heart when Diane Ladd smears her face with lipstick until it’s devil-red and then screams at herself in the mirror, or of Bob’s look of total demonic ebullience in Fire Walk with Me when Laura discovers him at her dresser going through her diary and just about dies of fright. The bad guys in Lynch movies are always exultant, orgasmic, most fully present at their evilest moments, and this in turn is because they are not only actuated by evil but literally inspired: they have yielded themselves up to a Darkness way bigger than any one person. And if these villains are, at their worst moments, riveting for both the camera and the audience, it’s not because Lynch is “endorsing” or “romanticizing” evil but because he’s diagnosing it—diagnosing it without the comfortable carapace of disapproval and with an open acknowledgment of the fact that one reason why evil is so powerful is that it’s hideously vital and robust and usually impossible to look away from.
