The film is horrible with:
1. Illogical narrative.
2. There's no significant problem that the film address or highlight.
3. The acting is horrible.
It seems to me like the film just tries to be unneccesarily emotional and in fact deals with no real life problem. It seems like the most meaningful thing in the film is In-yun which is lame and who needs to know how many past lives we have met!? Aurthur is the least horrible actor :) and imo the most nuanced character.
