This is the kind of drama that I love to watch. Im Siwan's acting was amazing and Lee Dongwook as a psychopath killer? That role surprisingly suits him well. I absolutely agreed with the Korean Hannibal-Will thing. The other casts did a wonderful job as well in bringing their characters to life. Especially Park Jong Hwan who played the twins.

I loved the way the tension was built. The directing and the editing made the whole mood amd atmosphere unsettling and creepy. I couldn't help but feel nervous whenever a character was in some kind of danger with one of the residents. And the way the story ended was just *chef's kiss* Ambiguous and left enough room for doubt. Also, the soundtracks were all such a bop.
