Whoever labels film genres at Netflix needs fired. "+1" isn't horror. It's more like a Neanderthal targeted frat brat party film written by Steven Moffat. It's about a bunch of douchbags and bimbos at an over the top college party. Then they have a black out and temporal clones of theirselves from 15 minutes past appear. Then with each blackout, the clones vanish and reappear closer on the timeline and more paranoid over and over until they they tear each other to bits. Then the time lines line up, everyone is alive and feeling creeped out. I wish my double had picked a better film.
