This drama has a lot of going on but there was nothing really happening, There was no beginning for each characters , they were just happened to be at the apartment at first and then suddenly some characters came until this last season I guess, then the crazy scientist came and then later a crazier scientist came as seems the villain at this drama and then Cha Hyun Su , someone who was able to control himself from being monster and then at the end they became one, and good looking soldiers getting killed by a monsters that seems like cars that transformed into human shape HAHAH , and then at the end there was this Neo Human , human or monsters with no emotions but has a memories .. I did not know if Hyun su was able to retrieve back everyone at the end their human .. maybe not
What I did understand behind about this drama is my review title itself .. the drama has shown that one when not able to control their desires becomes monster and live in a dream inside .. same as in reality .. we are all monsters who has desires when we are not able to control them , sometimes we become cruel , example when someone who's world is money sometimes they kill, sometimes they deceive others, they rob , they confront and worst they hurt themselves to get what they want .. For some reasons I think the reason why I was able to finish this one is the visual and props production, the action parts the actors too I guess .. butnot gonna rewatch this one .. worth watching ? nahh.
