This movie had potential...but while it wasn't a bad movie, it failed to live up to it's potential in my eyes. It didn't explain why anything really happened, and the last 5 minutes left me scratching my head. Other than that, i LOVED the use of foreigners speaking perfect Korean as the two side characters. The music conveyed the mood perfectly. As for rewatch value, it's an alright movie to rewatch. Overall this movie is getting an 8, mainly because i felt like it didnt explain a lot of stuff.
