Not 10 surely, but here are three that you might not have heard of... Just might scare you and she both. In general, these films work by breaking the rules.
Session 9 (almost an entirely male cast - In an unpredictable setting)
May (A creative new take on Shelley's Frankenstein)
Audition (Japanese film) Has the honor(?) of having more people walk out of the theater than any other film in history. This one goes waaay too far.
As a horror movie aficionado, I like these films because there are NO spring loaded cats. They twist the genre, and earn their scares.
