So much potential on the premise yet so little has been done to its storyline, let alone the style of shooting and overall structure of the drama. There's a mutant, a serial killer, bunch of thugs, and that's pretty much it, the story didn't really progress a lot despite having shorter runtime. The gore content also does look somewhat cartoonish where of course they're taking reference from that famous comicbook superhero production you know it. At least Jung Hae In and Go Kyung Pyo still did their best in their acting skills, which is the only thing appreciable in this drama.
