Sean Baker’s Red Rocket (aka “Dog Erection”) teeters on the line between mostly legitimate film festival-smarthouse cinema and relentlessly depraved and disgusting sociopath-porn. It’s “good” in the sense that Baker isn’t afraid to dive into gross and reprehensible behavior, and because he doesn’t feel obliged to deliver some form of moral redemption for the lead sociopath (i.e., “Mikey Sabre”), and because he occasionally flashes slick chops and whatnot, but the scuzz factor is REALLY rank. It was not a pleasant sit, but that’s the point, I realize. The Galaxy crowd totally hated it — a quick shattering of applause and then silence and hasty exits.
