A really good horror comedy be it intentional or not is a rare beast indeed.....
There are 2 that I come back to time and time again and always go down well when I have friends over:
Nightmare City has it all, great sound track, amazingly bad acting/script/effects, epic contrived ending. Also one of the best panning shots in motion picture history....maybe a slight exaggeration there
Dead Heat: Great spin on the standard buddy cop movie. Awesome camp dialogue, pure 80's trash.
Both have so many rewind moments.....
So my question is what is your favourite horror comedy?
