This is one of those dramas that were built piece by piece, a drama where there was care from the selection of the cast, as well as in the purchase of the rights to the Webcomic it is based on. The entire plot up to the final moment of the drama is well tied together, and everything that happened in the drama was developed meticulously by the screenwriter. We must note the well-directed scenes and the quality of direction and characterisation of all the characters.

Choi Woo-Sik, although surrounded by some controversies outside of his profession, is a complete actor and knows how to convey the most varied emotions in a dense drama, but at the same time with a comedic and irreverent tone. A work that mixes murders, blood, and comedic elements, in proper proportions, strongly resembles Tarantino's films Django and Kill Bill, where violent humour and blood go hand in hand.

The villain Song Chon, portrayed by the excellent Lee Heen-Jun, was literally built with seven hands, the environment and the people around him made him into this bloodthirsty and ruthless monster. My favourite character was Roh Bin, also played by the excellent Kim Yo-han, who brought life and charm to a heavy drama surrounded by violence. He was another character who life and environment made become this way, a nerdy vigilante who loved Lee Tang fraternally until the very end. His death left me saddened, but I saw it as necessary for the direction the drama took.

Although the ending was slightly open-ended, I understand that the drama fulfilled its purpose and the story does not need any continuation.
