The violence and set pieces are incredible in this film, if you can stomach it. There's a straightforwardness and realism to director Park's violence in Night in Paradise. Similar to the often-cited brutality of Park Chan-wook's Old Boy or Kim Jee-woon's much gorier and equally violent I Saw the Devil (also written by Park), the violence happens fast and hits hard, and the deaths often last just that extra little while. While there are a few instances that scream "how is that possible?" for the most part, the gloomy and bleak atmosphere succeeds in disrupting the viewer of any hope for a happy ending. Loved ones die, unfairly, unjustly, and yet, the world goes on, and very few people, especially gangsters, care at all.
The film suffers, however, from being too long, even though the slower, more touching scenes do give the two main characters depth and a chance to develop their relationship into something that will be sad to lose. The film also suffers from a few cultural translation ambiguities, like for instance, the film's title, Night in Paradise, which, for many non-Korean viewers, might suggest a romantic film or adult drama without brutal violence. In Korea, however, Jeju Island is often referred to as "paradise" (also, "Korea's Hawaii"), and the title is meant to connote a kind of juxtaposition between this paradise and the vicious, bleak, and merciless gangster world.
