Toxic Fletch
Beneath its wanton gross-out factor is an actually funny horror comedy.
I turned this movie off after 20 minutes and really didn't want to continue. Forcing myself to watch it further, it actually improved, and considerably.
The plot of this basically is a janitor in a hospital has a date with a girl in the morgue. She's dead of course and died of radiation exposure resulting in him getting some super-STD, turning into a zombie, seeking out vaginal blood, and infecting several others. Along comes a group of high schoolers on their way to a beach weekend and pulling over at a roadside hotel in the town to stay over the night. But they didn't plan on the horny dead making an appearance.
An experiment in excessive gross-out this movie...
