On the left you'll find a list of links to pages about what I believe are the current best Asian horror films. However, that doesn't mean there aren't any better ones. Other films I recommend are: "One Missed Call," "Audition," and "Whispering Corridors."
If you don't like one of the films I have chosen, don't be discouraged. Everyone's taste is different and not all Asian horror movies are the same.
