The film that gave
The film that gave me the greatest sense of horror comedy of all time was the "Black Meth" film by Sam Raimi. I am a huge fan of Sam Raimi's work and the quality is definitely there. The premise of the film is that a group of poor people are murdered by a gang of thugs who kill and torture some of them. This leads to a bizarre twist where the killers are brought to a drugstore.
The film that gave me the greatest thrill is, of course, this: the very first movie I saw the fall of the Berlin Wall. I'd been in the US prior to that and I'd seen a lot of films with lots of adventure and excitement. Before I saw this film I had no idea what it was about. I was not a huge fan of the movie but I can tell you that I had no expectations of the movie.
