I both love and hate this drama. The plot is unique and acting is amazing. I loved the fact that everytime Donk Sik would quote a movie there would be a vhs tape next to him . But I think that this drama could’ve gone another route. Although he had amnesia, why was he so keen in embracing his psycopathic tendencies. In my opinion it would’ve been great if he actually turned out to be a psycopath. Secondly, too many plot holes with Seo In Woo. Those random clips of him as a child, and then Donk Sik’s mention of his mother right before the big fight left me wondering. I wanna know what happened to Seo In Woo’s mother, rather than focusing on the superficial side of this serial killer the drama should’ve explained more his background. Again it would’ve been amazing if Seo In woo and Donk Sik teamed up and became killers together. Like Strangers from Hell , dramas don’t need happy save the day endings. It would’ve so awesome.
