We all agree that “The Canyons” is going to be just the worst, right? I mean, Lindsay Lohan can’t act anymore (or communicate with regular humans), James Deen acts in questionable pornographic films with “Teen Mom”s but gives us little reason to be interested in him as an artiste, and Bret Easton Ellis, who wrote the script, is a pompous windbag who offends gays every time he tweets. Every single teaser trailer that has been released has been more faux-hipster-artsy than the last. Finally they’ve released the official, full-length trailer and by God, does it confirm every expectation we have about this film. And yet … I know I’ll end up seeing “The Canyons.” But I don’t know why.
