The idea is very interesting, the movie is just some personal stories maskeraded behind a "fantastic" scene where death and life are together.
The main question is how far can we go to fight/live with our feelings/emotions ? what's the value of the past, the present and future ?

I really enjoyed watching it, was expecting some supernatural things, but it was all human, no need to look far for something inside you.

Good scenario, good interpretation.
Rating: 12+ (not really gore, since hrm .. i watched it).
No sex, very few nudity.
