Narrated by Michael Cera, oops, I mean Jesse Eisenberg, puts emphasis on the zombie rules of survival, for example rule 23 is the buddy system (here). Yet while these rules are comical they are completely ripped off from "The Zombie Survival Guide" by Max Brooks, yes, that is the son of Mel Brooks. His book was so successful that the sequel "World War Z" is being turned into a movie by notorious zombie slayer Brad Pitt.
While this fact kind of ruined the movie for me, for the casual non-nerd (aka the greater population of the universe) the movie should be a fun, albeit not best picture worthy film. It hits the right plot beats, there are some great kills, and some original laughs. Chances are you probably already know if you're going to see it or not. So go ahead, enjoy it, just know that the writers Rhett Reese and Paul Wernick could be some real deal literary zombies, feasting on other people's creative blood.
