The first part of the movie is actually pretty decent; it’s fast-paced, tense, and you feel bad by Kwon, who is accused of a terrible crime he didn’t commit, and is sent to prison. Once he escapes, though, the movie goes completely off the rails. It's pure action (this is not bad per se, but in this case, it is) with zero character moments (or development) and a moustache-twirling villain. There’s nothing new, exciting or compelling about this, and I won't feel the need to rewatch it anytime soon.
