We're asked to accept a lot in this movie about the teenagers and citizens of the town of Dilford. Here, humans, vampires, and zombies semi-peacefully co-exist. That is until the aliens show up and paranoia turns them all against each other. The vampires are evil and manipulating, the zombies are brain-obsessed eating machines, and the teenagers are, well, teenagers.
At its core, Freaks of Nature is a good old fashioned 1980s teen sex comedy in the mode of Fast Times at Ridgemont High or Better Off Dead, more about the kids and high school than any of its supernatural and science fiction trappings. No matter what camp you fall into, it's all about fitting in and dealing with parents and growing up.
As the aliens make their demands known and the factions in this weird town must come together, things get even weirder, but it was cool. I actually enjoyed this a lot more than I ever would have suspected. And the supporting cast is full of great comedic actors including Patton Oswalt, Keegan-Michael Key, Joan Cusack, and Denis Leary. Recommended, if you can catch it on cable (or if you lose your remote), check it out.
