I'll need to watch the Korean version now, to see how they compare. I felt that, for me, there was a lot of useless filler in this movie, going for the comedy angle. It was hard for me to relate to the main character, because they never really delved into why he was so determined to commit suicide. Everything eventually got tied up/explained/resolved, and once that happened, it ALMOST made up for the beginning. I was sitting at about a 5/10 rating through most of the movie. Best plot twist I've seen in a while.
