Without a list of what you’ve already seen, I’m reluctant to go over the classics that I’m sure will either be mentioned a dozen times, or you’ve seen a dozen times. However, if you haven’t seen it, try The Orphanage, a Spanish horror film, a great one, about a woman who is adopted, returns to reopen the orphanage she came from. It’s not just a fantastic horror movie, it’s a fantastic movie in every sense of the word.
Also, not nearly as good as the above, maybe set a goal to catch all of the movies featured in the past two Horrorfest film marathons: http://www.horrorfestonline.com/
I’ve not seen them all, but Gravedancers is a fun, scary film. The Abandoned and Wicked Little Things are also worth a watch. Penny Dreadful not so much, and Dark Ride is not great, but is a nice homage to early 80s slashers. Reincarnation is good Japanese horror if you are into that kind of thing, but not particularly noteworthy (unlike the outstanding Ring, The Eye, and Ju-on).
I can’t help you with your favorite genre, but nothin’ says “creepy” like The Shining. I love this movie. It’s beautiful to look at and has a deep and ominous vibe that never lets up.
Let the Right One In is the best movie I’ve seen this year. It’s a Swedish vampire film that is in limited theatrical release in the U.S. currently, but debuts on DVD in March 2009. It’s not too early to put this little masterpiece in your Netflix queue.
I recommend a book – Stephen King’s Danse Macabre, which includes a sort of critical survey of the horror-film genre and introduced me to a lot of flicks I’d never heard of. Including some which are frightening even though there is no actual violence, or what there is happens off-camera.

Angel Heart. Mickey Roark is a PI, searching for a disappeared WWII veteran and Sinatra-type singer in 1950s New Orleans. Oddly, everyone he meets keeps getting murdered in some horrific way. Very, very disturbing film.
Dagon - If you like H.P. Lovecraft, you’ll love it. If you’ve never read Lovecraft, you’ll want to after seeing this.
