Query: One of the worst I've ever seen

I've watched a lot of low-budget zombie films, and this is truly one of the worst. It was more a loosely connected montage of gory set pieces than a fully realized film with an actual story, and when the story does seem to finally kick in, the movie pulls the rug out from under the viewer's feet. Absolutely terrible.
