Ji-Woon Kim is one of my favorite director's working, and I've only seen two of his movies. One of them, Joheunnom nabbeunnom isanghannom (aka The Good, The Bad, The Weird) is one of the most exhilarating theatrical experiences I've ever sat through.
Choyonghan Kajok (The Quiet Family) isn't quite as frantic and post-modern. In fact, it is simplicity itself: a family retires to a remote mountain in South Korea to open an inn catering to the hikers. And their guests keep dying: suicide, murder, pure bad luck... the movie is a pitch-black comedy so dry that occasionally I wasn't sure if I was supposed to be laughing.

The trailer might be worth noting for the use of two decidedly western pieces of music (both used in the film itself), and for the presence of Min-sik Choi (the lead in Old Boy) and the truly wonderful Kang-ho Song in one of his first performances.
Takeshi Miike, the diamond dog of Japanese shock cinema, remade The Quiet Family- already a fantastic movie, as a musical.
My wife, who is pretty strongly anti-Miike, is strongly considering lifting her ban long enough to watch that.
The original, as it's trailer hopefully attests, is well worth your time.
