Gonjiam but with a psychic trapped inside

Unoriginal, almost effortless visuals, just your typical pale gray black-eyed long-haired ghosts giving their victims spine-tingling back and shoulder massages. Plot-wise, the only unique concept was the psychic being able to time travel through the haunting events of the center and being able to exorcise the victims of that time frame. But most of it was much like Gonjiam with a boss ghost and your occasional possessions here and there. It was predictable despite its inception-esque concept and honestly a bit boring for my taste.

quick explanation why you should watch

So I will begin by saying that the comments here are very 'this would have been good if-' type of thing. I just finished this movie and won't beat around a bush. The ending was both predictable and you wouldn't see it coming at the same time. All in all it was not completely satisfying to make you lose all the built up suspense that is why many people blame ending for this. I wish it ended different but I am also amazed by how different ending it was compared to other movies. Usually they drop the suspense by ending and decide to ether make it happy or unhappy one, but this movie kept the suspense going until last seconds.

I try not to put out any spoilers out here because I hope this will be the reason why you decide to watch this instead of listening to others and not give it a shot. This lowkey became one of my favorite asians movies AND I AM GLAD I WATCHED IT WITH LIGHTS ON. This is one of creepiest movies I seen, it was well executed and always kept the right atmosphere on.

Did you see movie Grave Encounters? It will have similar moments from there which I honestly love because it takes traits from The Stone Tape theory and more.
