Directed by: Chan-wook Park (2006)
Pros: interesting characters, some humour
Cons: abrupt ending
Cha Young-goon (Su-jeong Lim) is convinced she's a cyborg in the way her grandmother was convinced she was a rat. When Young-goon stops eating she's sent to a mental institution where she meets a unique group of people including Park Il-sun (Rain). Il-sun is a thief with some remarkable abilities.
This is a strange film in that we're seeing things from Young-goon and Il-soon's points of view. As both of them (and the other inmates around them) are unreliable narrators, it's sometimes hard to judge what's really happening. There's a fair amount of humour, which was appreciated, as well as a sad storyline regarding Young-goon's grandmother. There's also some stylized violence and hints of romance.
The ending was rather abrupt and didn't tie much up, but on the whole it was fun to watch.
