Damn, talk about an open-ended question!

I have around 700, and there are thousands more. I guess I would start with the "Famous" or well known horror movies like The Exorcist, The Omen, The Evil Dead Series, The Hell Raiser Series, Night of the Living Dead, Dawn of the Dead (original) and Day of the Dead, then branch out to the B&W Classics (Phantom of the Opera, Hunchback of Notre Dame, Frankenstein, The Wolfman, Dracula, Creature from the Black Lagoon) then branch out even further to the more un-obvious (is that a word?) movies that mainstream audiences may not have heard of like Dog Soldiers, Night of the Demons, Seven Doors of Death, JU-ON etc...

Read horror movie forums like this one and see what everyone's talking about. There is a variable warehouse of knowledge regarding horror movies on this site. All you gotta do is pay attention and read.
