Spider Forest is one of those films that not everyone is going to like, but I for one thought it was excellent. Unfortunately it is difficult to describe the plot more than it already has been in other comments as knowing too much about this film will spoil it's magic.
This is a dark, intricate, intelligent, atmospheric and somewhat spiritual movie in my opinion. Certainly worth seeing for anyone who likes to walk out of a cinema with questions floating around their heads.
Great performances, characters, cinematography, direction, and one of the most interesting scripts I have seen in a while. This has probably been billed as some kind of horror or thriller genre film, but to me it is more human drama or art-house film. Korea is becoming the best place to find films that weave intricate human stories into other genres of film to elevate the stories above the competition.
Spider Forest is definitely a great piece of cinema that will make you think and will stay with you well after the credits roll.
