For me, this movie is one of the 'hard-to-digest' movie but leave a very deep meaning in our heart.
The movie talk about how the family that nearly broken face the misfortune together. Parent's love is really amazing, but sometimes on the other side it can destroyed other people.

In this movie, in order to keep their daughter alive, the father asked one of his subordinate to try out his research to his daughter. Happy with the result, the subordinate drowned to the matters and second think of his personal matter and relationship. The mother give all of her love and attention to the daughter so that the daughter doesn't feel alone, but her action make his son feel unnoticed. She even didn't realize the feeling of his son.

Many tragedy and emotional scene in this 120 minutes movie. One tragedy, many butterfly-effect and one solution. Sometimes I didn't agree with the mother, but if I positioned myself in her position, I think I will act the same.

All of the casts acts very great! Awesome! I didn't feel I watch a movie. It's like watching a documentary.
