Like horror has blood. A tossed salad of scenes whose relationship makes only a klutzy kind of sense. Combine this with the worst directing, photography, sound effects, and music imaginable and you have some idea what you're in for. Night scenes too dark to see the characters. A woman screams but no sound comes out -- they forgot to add it. A zombie wraps his arm around someone and they scream and fall dead to the ground. A man being shot grabs his chest before the gun goes off. Or how about the score -- a psychotic killer is chasing a woman and her child with intent to kill, accompanied by swinging jazz. This chase scene incidentally is most of the movie, or seems like it, killer running, woman and child running, killer, woman, on and on ... Zombies and mad scientist plot elements are stuck onto it with spit and string. To say this is a cheesy horror film is to be generous. Someone said it had never been used on MST3K -- that's probably because they'd be putting more work into ridiculing it than the filmmakers did in making it.
