When I read the story i liked that there are some people in the heroin's brain whom discuss her actions and tells her what to do.
The actors were all good, except for the heroin. The heroin acts like she is a robot !! maybe its because of the actress. I gave a low rating for the acting because the heroin is the most person who appears on the screen -_-
In addition, the movie was a bit long and boring which made me skip a some parts at the end.
Anyway, i liked the ending, it is realistic
However, i will not watch again, since i do not like this kind of romance and  plot. 
Overall, i do not recommend it.
