Going by the title, the film is about zombies. Though filled with extreme gore, people are shown being literally eaten by killer zombies and the four main characters constantly kill zombies in graphic ways, I still found it entertaining. Narrated by Jesse Eisenberg as his character "Columbus" or "Ohio", his explanations made the movie that much better. Sex isn't a problem other than a few mentions of "hitting that" and some talk. There's one kissing scene but it's not bad, actually it's quite sweet. I can recall only two scenes where drugs/drinking were involved: When Columbus and Tallahassee first meet, he offers Columbus some sort of alcohol, but when he's not looking Columbus tosses it over his shoulder without drinking it. When Wichita and Tallahassee meet Bill Murray (playing himself) they smoke marijuana from a hookah. Tallahassee is a little obsessed with Twinkies. Abigail Breslin plays a 12 year old who assists her sister Wichita in several schemes that involve Columbus and Tallahassee as the victims. She also seems quite calm, almost too calm, about the whole aspect of killing zombies and it is a common sight throughout the movie to see her carrying a gun or some other weapon. Maturity plays a large role as far as comprehending and dealing with the content of this horror/comedy film.
