Planet Terror is half of the Grindhouse collaboration between Quentin Tarintino and Robert Rodriguez. These two films are an homage to the double features that played in grindhouses. This is the better movie of the two in my opinion. Here's the summary from IMDB.com: After an experimental bio-nerve gas is accidentally released at a remote U.S. military base in Texas, those exposed to the gas turn into flesh-eating, mutating zombies out to kill. An assortment of various people who include stripper Cherry, her shady mechanic ex-boyfriend Wray, a strong-willed doctor, the local sheriff, and an assortment of various people must join forces to survive the night as the so-called "sickos" threaten to take over the whole town and the world.
This movie is completely over the top and dripping with cheese. There are horrible puns, bad acting, and over the top effects. The film is digitally aged to get the look of 70s films. This coupled with pop culture references and modern technology make this film utterly unique. All of these aspects mean that this movie is so bad, it's good.
This is not your normal zombie film where people hole up in a house or a mall and barricade it against zombies. They actively fight against the zombies. Much of the film takes place on a military base and a hospital. Plus what other movie has a character with a machine gun for a leg? Watch this movie if you're in the mood for a funny cheesey gorefest and want to watch something entertaining. You won't be disappointed.
