What are your top 3 favorite Korean Movies?

Hi! I love Korean series and Ive seen lots of them nad I like lots of them but I only have one ultimate favorite when it comes to series and that's Fullhouse with Rain and Song Hye Kyo, very funny and quite romantic. Since you are talking about movies and not series I guess I can only say that Ive only been able to watch two of them. One is "Arang" which is a psycho suspense thriller and Julian from My Girl was the leading guy. Then the other was "My Girlfriend is a Cyborg" with Rain as the leading guy and the setting is that they are in a mental facility and the girl he likes is a cyborg that all the other people just think that she's crazy and they've been trying to let her eat. Its really a crazy world and Ive never seen Rain act so kooky before that movie. Ive always wanted to watch My Sassy Girl but I havent yet until now. Maybe when they show it on tv Ill be sure to catch it.^_^
