I legit have no words. This show is a game changer. Personally I didn't find it that scary but the ending, when the officer realised Jong-O killed everyone.. I had chills! You need to watch this! The acting is so spot on its like watching a documentary. The quotes in this film are so deep too! Like when Moonjo saw Jong-O go insane and said "You are the best piece of art I've ever created." BRO. Its kind of sad too because Jong-O was normal and happy at the start. The residence destroyed an innocent man, and the innocent man destroyed the residence. Highly highly recommend
