What would a Halloween movie marathon be without things that go bump in the night? Monster's of all shapes and sizes have been terrifying us for decades. Personally, these are my favorite kinds of horror movies. Give me vampires, werewolves, satanic dolls, clowns, zombies, and the genetically altered any day!
A few years ago my Dad called me to talk about a movie he had seen. All he could remember was that it was Scottish, had werewolves, and was awesome. Cue a few months later and he's figured it out and bought this movie for me. Wow, was he right! Marshal has a tight script that kept me enthralled from beginning to end. The pacing is steady and the twist at the end seems to come out from left field (you may figure it out just before it's revealed, but nothing will be lost). I highlight this film as another reason CGI should be used only in extreme circumstances. The practical FX here are more terrifying and bloody because they are real. If you haven't seen this movie, queue it up immediately!
"An American Werewolf in London" - see my review here
All I needed to know to see this movie was it starred Nathan Fillion and Michael Rooker. Sold! I literally fell out of my seat in the theatre laughing ("That looks like something that fell off my dick in the war"), then covered my eyes a moment later.
See Also: Child's Play, Dolls, IT, The Howling, Wolfen, The Hunger, Piranha, The Blob, It's Alive, Pumpkinhead, Skinwalkers (it's so bad it's good), and Meet the Applegates (not a horror movie per se, but giant Amazonian bugs disguised as people is hilarious),
