Are you cool with gore and really bad language? Good, then you are going to love this movie. Am I a bad mother for allowing my son to watch it? Yes, probably. But this was right up his alley. He already has been informed of the "bad words" and is threatened within an inch of his life for using them.
This is not a serious movie really. It is insanely over-the-top with regards to undead flesh-eaters chasing and eating live humans, and can be very disgusting, but throughout the entire flick, we were laughing until our stomachs hurt.
Columbus (Jesse Eisenberg) is a studious young college student who is just a dude trying to survive the zombie apocalypse. He has made it thus far by following 30 important survival rules which include Cardio (to effectively outrun them), The Double Tap (two shots to the head just to make sure), Always Look in the Back Seat, or Avoid Public Restrooms.
On his way to Ohio to see if his parents are still alive, he runs across a Twinkie-obsessed redneck Floridian named Tallahassee (Woody Harrelson), who helps him in the struggle. Later they happen upon a beautiful young woman and her "little sister" (Emma Stone and Abigail Breslin), and the four head out to LA where they hear there is a zombie-free amusement park. There is alot of shooting, zombie-slaying, some furtive glancing between Stone and Eisenberg, and its all just a madcap bunch of fun.
The highlight of the movie for me was when the four survivors break into Bill Murray's house in LA and find him there, disguised as a zombie, hiding out and drinking his stash of expensive wine. Most wacky. Scene. Ever. In the best possible way.
