3. Troll Hunter
Troll Hunter is a 2010 mockumentary about a group of college students who attempt to film a documentary on a supposed bear poacher. However, as they investigate our hero, Hans, they discover he works for the government to keep trolls away from populated areas. He says, that, apparently, these grow more aggressively daily, and he must figure out why. Though a lot of the humor goes over foreign audiences' heads due to its subtlety and its cultural cues, the film is still one of the most entertaining monster movies I've seen in years. It takes an interesting approach to a beast you rarely see in TV or film. Plus, it plays with the lore from all those childhood stories in such a fun way that you can't help but love.
