Sorry Folks--its a total waste
I have to begin by apologizing to everyone who will be offended, but the movie is worthless. It doesn't do anything to reveal any inner truth about Lynch, as an artist, or as a Director, which is really disappointing to me, since I am also one of the many Devotees of the man. Most of us think of him as something of a Messiah, and are willing to worship at the altar of whatever the heck he drivels out, and so this confusing and unfulfilling documentary is exactly what we all deserve.
I'm about to tell the truth to anyone who's willing to listen: this movie is a waste of time. I don't think the person who pretends to be David Lynch (by using the silly name blackandwhite) is really much of a filmmaker at all, I think that he's just a film student who was one of the many that we watch onscreen, dutifully making David feel like his every whim is satisfied by pandering to him.
David Lynch himself is more than a little constrained by a cage of his own making, every so often admitting that he has no idea what he's doing, and feels a sense of inadequacy about much of what he does, He actually blurts out in one very honest moment that he's really very depressed, (but when talking to people on his website, he manages to convey a pretense of the opposite, and people seem to buy into it.) I have met the man and found him to be sincere, and an "aw-shucks" kind of guy, with little to indicate that he's anything more than a kid who inherited both a candy factory and amusement park, and just wants to give everyone a ride in the funhouse. David Lynch is kindhearted, and if he were not a filmmaker, would probably just be a friendly neighborhood eccentric.
But that doesn't discourage anyone in the audience, who all come to find some secret mantra about whatever the gobbledegook he prattles all the time. One guy in the restroom afterwards, in a desperate attempt to sound cool, stated, "I totally, totally get what he said about the fruit." (Yes, he said totally twice, just to make sure that we knew he got the hidden mantra of whatever the hell David said about art being fruit, or maybe it was the meditation being the fruit, or whatever else. (Most of what David says just doesn't stick in one's head, but no one would ever really admit it, they just act like it's profound so as not to seem uncool.)
So my friends, this is yet another blatant example of the Emperor's New Clothes, only this time the Emperor is somewhat loosely clothed in a buttoned-up white shirt and kahki pants (does he really have any other clothes, or is his entire wardrobe just one outfit?). All told, this movie is an unmitigated bore.
