Just thought I'd share a gem I found: Noroi: The Curse. A recent release, the film is shot in the same style as The Blair Witch Project, being a mockumentary. Critically appraised for its surprisingly deep and complex plot, excellent acting with a cast of over 25 characters, and its unusual length for a horror film (two hours), it was highly successful in Japan and a genuinely frightening film. For those who specialize in the J-horror genre, it is worth watching for its departure from the usual J-horror elements and its fresh take on what is considered scare.
Noroi is available to watch online in several places, but I found it split into 11 parts on Youtube for those who don't feel like searching. I would highly recommend it.
For those who've seen it, what did you think? :)
