A young couple run into a deadly rural Blood Cult. Oh, and let's not forget that there's a guy named Jim Carrey (yes, that's the characters name.)
Written and directed by the guys that gave you "Shreik of the Mutilated", "Invasion of the Blood Farmers" is one of those really bad but hilarious cheap independent horror movies that came before the likes of "Halloween" changed the way horror is done. Much like "Mutilated" and "The Corpse Grinders", you can't help but laugh at the proceedings.
The acting is bad (when is it not in these kinds of horror movies?), the cult wears garb that looks like something a Klansman would wear, the movie is rarely coherent, and yet, you never feel bored while you watch it. It's the kind of horror movie that is insanely bad, yet is bad in an enjoyable way.
Fun fact: There was a great Doom Metal band named "Blood Farmers" named after this (well, yeah), who are worth checking out.
