some of my favourite recent scares have been:
Tale of Two Sisters - a superb Korean movie. Very weird, very creepy.
From IMDB:
Two sisters who, after spending time in a mental institution, return to the home of their father and cruel stepmother. Once there, in addition to dealing with their stepmother's obsessive and unbalanced ways, an interfering ghost also affects their recovery
Shutter - Another oriental one (Thai)
from IMDB:
A young photographer Thun and his girlfriend Jane discover mysterious shadows in their photographs after fleeing the sceen of an accident. As they investigate the phenomenon, they find other photographs contain similar supernatural images, that Thun's best friends are being haunted as well, and Jane discovers that her boyfriend has not told her everything. It soon becomes clear that you can not escape your past.
I haven't seen it myself, but Phone, a Korean movie, has been highly recommended a few times.
