I remembered Kim Ki-Duk from viewing Seom (The Isle) a few years back. I didn't particularly like the film, but it definately stuck in my head. So I wasn't expecting such great things from 3-Iron (a.k.a Binjip which means Empty House in Korean).
It's brilliantly directed, with strong fluid shots. It has a great soundtrack, full of mystery and ghostly appeal. The acting is practically flawless, and made even more accented due to both lead characters never exchanging spoken dialogue.
I have to say I love this film. The sweet & sour and yin & yang story line is just beautiful to watch and absorb. The film is full of symbols, and requires a second viewing to fully take it all in.
I think most people will either love this film or think it pretentious. The ending isn't so ambiguous as some of Kim Ki-Duks other films, but still leaves a lot to your imagination. It's my film of 2005.
