Krampus has a weird tonal mix, which could be a criticism, but in this case, it means that it is a lot of fun. Really, it is the only approach that makes sense. How else is it supposed to feel when a giant goat creature and his freaky minions are terrorizing you? The narrative swings include going back and forth between family members being awful and lovable, between the characters standing a chance against Krampus and having no chance at all, between an insulting ending and a perfectly ambiguous one, generally managing just the right balance through it all.
