I recently saw Bunshinsaba, and I'm less than impressed. I think the story wasn't very good, if even a bit stereotypical. Vengeful spirit, horrible curse, etc etc. (I suppose, though, after being quite used to movies like Ringu, Ju-on, Phone, and the like, things like that really aren't scary. So maybe some people would find it frightening.) I've seen both Phone and Nightmare, directed by Ahn as well, and I liked those better than Bunshinsaba- I wouldn't say Nightmare was very notable either, but Phone was very very good. So I was expecting Bunshinsaba to be pretty decent. Not scary at all, but it did manage to keep me somewhat interested for the most part.
(And I gotta say, it really amused me that there was a Dollmore doll in the movie.)
