From the acclaim it got I was expecting more from a Korean horror if it's going to be viewed in the same caliber as A Tale of Two Sisters, as some other reviews have stated. This movie isn't in the same caliber except in budget spent on special effects. Think Amytiville horror. With a tree and sparse dialogue.
If you're going to have a movie with limited dialogue, the plot line and characters have to carry the film. This film could have been told quite well in a 30 minute short film concept, 2 hours with a lot of staring at trees and terror scenes that make you not only not scared, but detract in a "What the..." sort of way does not a good horror movie make.
Those people who are stating that this film gave them lasting impressions must literally have heart attacks when decent horror films lay it in.
