"Zombie Nightmare" is appallingly bad. I've seen plenty of low-budget productions and few compare with the complete misuse of resources here. There's one scene where a zombie chases a girl through a recreational facility with embarrassing cuts back and forth between the girl who is 'leisurely jogging' as the MST3k bots put it and the slowest and least menacing zombie in the history of film.
This is one of few movies which is actually just about unbearable without either teaming up with a bunch of people to rip it apart or watching the MST3k version (which is hilarious, by the way, one of the best). The only things remotely entertaining about the movie are the laughably bad sexual innuendo and the obvious: Adam West. Let's face it, Adam West is just entertaining in any setting. Other than the sexual innuendo which really is laughable, there's not much here to enjoy even on a 'so bad it's good' level- it's just BAD.
The film boasts one of the funniest and weirdest title sequences I've ever seen, and one which leads to a hilarious conversation about "Ace of Spades" in the MST3k version.
Watching the non-MST3k version just results in seeing more of the sexual violence and hilariously bad gore cut out of the MST3k version. I can't see why anyone that isn't obsessive like myself would want to watch the original version of this film. It's torture.
1/10 (10/10 MST3k)
