First of all, although the movie was named after a forest, most of the movie focuses on events outside the forest and what happens to people because of a cursed box known as Kotoribako. The film's photography is beautiful and very green and sunny, reminiscent of a forest, which doesn't contribute much to the atmosphere of suspense. The cuts between scenes are strange and there isn't much dialog between the characters about what's going on, which makes the pace strange. Maybe it's just because I'm not used to the rhythm of Japanese cinema, but Ox-head village (by the same director) had a much more engaging rhythm of intrigue and mystery than this movie. Even so, the movie is never so boring that it takes my attention away, with some creative scenes such as when a character takes photos of some drawings and receives flashbacks in her mind, or the people on the branches of the trees. It's not very scary and the monsters could use better make-up, but it's still a fun and exciting movie. Because I loved the ending, I'll give it an 8! But Ox-head is still the best of the trilogy!
