Im a fan of Korean films so I had to give it a chance. It wasnt bad, had some good build up and character stuff. The actors, especially the kids did amazing work. But where it starts to fall apart is the last act, especially the last 10 minutes. It seemed like they didnt know hot exactly wrap it all up. But def worth a one time watch. a 6/10 for me. If you are a fan of Korean horror, give it a try.
