Some of South Korea's output in recent years is very good; high production values and refreshingly different styles.
For someone new to South Korean cinema, I recommend in particular "The Chaser", "Man from Nowhere" and the original South Korean "My Sassy Girl" (which is far, far better than the trite, bland Hollywood remake).

(a little cheesey at times, and very "foreign", but really interesting. I heard rumors of a Hollywood remake that sounded terrible, so make sure you don't watch that one if it exists).
