An interesting question... How about those Hallmark Christmas TV movies? I've not ever seen any (because I'm in the UK, although I daresay you can still find them here if you look, which I don't want to) but I'm well aware of the formula and that they are the butt of many online jokes. From what I can discern, this is richly deserved. So yes, let's add a massacre or ten to these ghastly saccharine fests.
