How bad is it? It's a mishmash of genres that doesn't succeed (or fail) at any of them.
Should you see it? It has its fans. If cheap splatter's your thing, sure.
It's a kung fu film. It's a zombie film. It's a women's prison film. A voodoo serial killer of pregnant women is executed, but his spirit lives on and it's up to an inmate of a women's prison to fight him and his zombie followers with martial arts. The fight scenes aren't bad. The effects are laughable and the flying mutant baby zombie will make you laugh, despite your efforts not to. There's a few nice in-jokes (a guard is named Elsa Thorne) and some porn actresses show up, like Erin Browne (Misty Mundae) and April Showers.
