"A line has been crossed. You can't eat the teachers man." Clint (Wood) is a struggling writer who takes a job substitute teaching at his former high school. What begins as a typical day takes a strange turn when one student attacks another. Soon the entire school is under attack by a group of infected students and the teachers must find a way to fight back and survive. This is just a flat out fun movie. A real horror/comedy that actually keeps you watching and makes you laugh throughout. The movie is gory but not over the top and this is the type of movie that makes you laugh at things you feel you really shouldn't be. There are some really funny lines in this and the movie is worth watching if for no other reason then to see Elijah Wood's reaction to someone calling him a Hobbit. This is not a movie that will win any awards and won't become a classic but it's just fun to watch and one you don't have to think about. Overall, if you like movies like Tucker and Dale vs Evil you will enjoy this one as well. Nothing but a fun time. I give it a solid B.
