8/10
Must be my first Asian found footage and I have to say I quite enjoyed it. I did not expect much, but the scares were really smart done and the characters really delivered, all of them.
Reminded me of Grave Encounters.
Fun fact: They wanted to film it in the actual place in Gonjiam, but the South Korean guv. refused and they did it in Busan, but making the place as close as they could.
