All the interesting characterization from the drama is turned into a bunch of boring cliches and two of the best characters from the drama aren't really in the movie. Tae-soo (Jo Dong Hyuk) shows up for two seconds, showing he's "found God" (?) and that's why he isn't participating in bringing bad guys to justice. Jung Moon (Park Hae Jin) isn't even mentioned. They are replaced by "hot girl whose crime is scamming scummy men with her hotness" and "maverick, gifted young detective" whose crime was a criminal dying from a heart attack while he was chasing them. Which neatly takes the basic story line of"these are hardened inhuman criminals who are making up for their heinous crimes by catching other hardened inhuman criminals and so regaining some of their humanity" , WHICH WAS THE WHOLE POINT OF THE DRAMA and throws it in the trash. There is no character development, no reason to care about any of the characters and is honestly just boring. It's almost like the creators of the movie thought people liked the drama because of the fight scenes and not because of the complex, extremely flawed characters and the interesting plot. An utterly baffling "sequel".
