No Blood No Tears, the second feature by Corean action auteur, Ryu Seung Wan, isn't so much an action picture, but more of a pulp noir/caper movie like a number of the films of Guy Ritchie and Quentin Tarantino.
The story itself features a rather large cast of characters, but our protagonists are two women, one with an abusive ex-boxer boyfriend turned criminal and the other an ex-con turned taxi-driver who owes some gangsters some money. A somewhat complicated scheme is hatched by multiple parties to steal money from an illegal dog-fighting event and it appears as though multiple gangs are involved, as well as the police, some wannabe criminals. Once the scheme begins, all the parties go for the bag of money and multiple double crosses are revealed, along with fists flying, feet running and a whole lot of people getting beaten up and/or killed. All of which is clear, even if it's a little chaotic at times.
Humor is present in the film, more in the form of irony or just people (or the audience) reacting to the madness that's occurring, but it's not a comedy. The action is stylish and some of the choices in direction, including some crazy tracking over surprisingly long choreographed fight sequences, can be surprising both in effectiveness and audacity. The art direction is also notable, the film being drenched in dark tones, perfectly setting the atmosphere.
I think all thesps do a good job with the increasingly deranged boyfriend being the most surprising of all as his character changes. It's not an easy film to watch due to the heaping of physical non-glorified violence, so those that can't take such images should generally stay away. Also, if you don't pay attention or try to do something else while watching this film, you might lose track of what's going on due to the expansiveness of the cast. And things do get quite chaotic when multiple groups are encountering each other (and also quite amusing as well, in a maddening "can it really get any crazier?" kind of way).
Fans of crime/heist movies with a little grit and humor, like those of the aforementioned directors will find a lot to like here. I personally enjoyed the insanity, the comedy, some kick ass violence, but I did wish it would've relented just a little on some of the pummeling that happened. It sometimes just got brutal to watch such an unfair match-up. But overall, I enjoyed this energized, entertaining, funny sequence of increasingly crazy events. 8/10.
