Bloody, funny, gory homage to classic horror movies, especially of the B sort. James Gunn's debut feature is by a horror fan for horror fans, a tongue in cheek, over the top film about an alien invasion that turns the inhabitants of a small town into zombie-like monsters. Romero's "Dead" movies, Cronenberg's body horror, and Carpenter's "The Thing" are the most obvious influences. Nathan Fillion, Elizabeth Banks, Michael Rooker, and Jenna Fischer (who was married to Gunn at the time) head up a cast that is much better than you usually find in movies like these. Not for the weak-stomached. Gunn graduated to the big leagues last year with "Guardians of the Galaxy." Also check out "Super," "Tucker & Dale Vs. Evil," "Cabin in the Woods," and "Evil Dead 2."
