CHAPTER 51 Chapter51 is a mock documentary, a fake-movie murder mystery, a serial-killer comedy, and I don’t even know what else. I do know that it sits at the nexus of arthouse pretension and Hitchcockian gooner schlock; it’s silly, nimble, pretty to look at, obnoxious, and exhausting. It’s also funny. Every so often, in its feverish, inside-Hollyweird hurly-burly, it damn near transcends its film-school pretensions and stumbles into something that feels, dare I say, unique.
