I personally love terrible, suck ass, just plain god awful horror flicks
Intentionally or otherwise. I'll list a few.
Chopping Mall (1986)
http://imdb.com/title/tt0090837/ - Surprisingly, it's about killer robots with lasers...no chopping in the entire movie.
Dead Alive (1992)
http://www.houseofhorrors.com/deadalive.htm - So who's idea was it to let Peter Jackson direct Lod of the Rings after seeing this. Brilliant spoofy, gory as hell horror flick.
Dr. Giggles (1992)
http://imdb.com/title/tt0104139/ - Tagline: The Doctor is out... of his mind. Need I say more? Unholy sespool of a film ;P
Killer Klowns from Outer Space (1988)
http://imdb.com/title/tt0095444/ - I think we spent more time coming up with an entire back story for the fictitious homsexual relationship between the two lead guys in the film than we spent watching the movie. I think we got the better deal.
Ok, I'll leave you guys with one good one. This one's actually a TV Miniseries that was on in I think 1998 and video/dvd in 1999.
Storm of the Century (1998)
http://imdb.com/title/tt0135659/ - Written for TV by Stephen King and infinitely better than "Rose Red" or the crappy adaptations of his books. Very psychological. Mr. Linoge is a perfect villain as he's perfectly and unspeakably evil. And he doesn't pretend otherwise.
