"그놈은 멋있었다" is the title of a 2004 movie that I recently downloaded and watched. Roughly, the name geunomeun meoshiteotda translates as "He was cool" or "That guy was cool." It was a teen comedy-romance.
But I enjoyed it, as I spend most of my working days immersed in the world of Korean teenagerdom, and thus, although the movie is hyperbolic and romantic fantasy, it is also, at another level, a somewhat realistic portrayal of contemporary Korean teen culture. So, despite its genre limitations, I recommend it. It's available on youtube in about 14 segments, with subtitles, if you can't find it in your video store or are unable to find a good subtitled download of it (I found mine on silentregrets.com [update: silentregrets no longer exists – presumeably shut down by the copyright police])
I learned a wonderful and useful phrase from the movie: 정말? jeongmal = "really?"
The lead actress in this movie, 정다빈 (Jeong Da-Bin – a screen name), committed suicide in 2007, suffering from depression. A quote associated with her is: "I'm complicated and I feel like I'm going to die…I have lost my identity."
