This movie is fucking awesome. Yes, it's two movies. It's supposed to be a kickback to 80s double features. The first movie is directed by Rodriguez and is a zombie movie, it was amazing. In between the two movies are fake trailers for movies that don't really exist. The highlight of the entire thing was the fake trailer for a movie called "Thanksgiving". The second movie is the one directed by Tarantino, and it was great too. If you like 80s sleaze/exploitation movies, zombies, gore, and have a morbid sense of humor, this is the movie (movies?) for you. Otherwise, don't bother. It doesn't have any of the boring stuff like production values, or cinematography.
edit: Highly reccomended to iago, I know he likes bad movies just as much as I do.
