Could be great if remade in Hollywood with a better script, plot and a decent budget
This movie starts off good, but like a lot of Japanese horrors, the actual scares & effects are lame to downright laughable. The twist at the end made the already weak movie worse and still left a lot of questions unanswered.
If Hollywood remade this with a good cast, script and made it a supernatural horror (no more zombies please) without the final twist, it would make for a great watch.
