owes a lot to dawn of the dead (the idea, the shopping sequence – including the pop music that accompanied it, the themes and more), day of the dead (the zombie on the chain sequence in particular), and a bit to lord of the flies. but it’s not a complete rip off film, and even if it were, it’s still pretty damn good. the characters are well acted and the direction is very good. the grainy dv “film” used is perfect and goes along with the sets and stilted angles that everything is on. the dvd transfer actually makes the movie look better than it’s supposed to.
