Everything fits together to create this unique experience, you start by watching the background story, the development of the events, and when you reach the end everything is unveiled. The story seems good, nothing exceptional, but this is just part of the experience. Expertly guiding the viewer through the events leads to the extraordinary climax at the end, releasing all the bottled up emotions carefully placed in your mind through the characters. Only at the end you will understand what is all about and understand how amazing the movie is.
The soundtrack isn't much noticeable except the ending theme that accompanies the realization after the shock you just witnessed, it just feels right to let it play while rewinding and going thru everything that happened.
Everything else is just superb and this is one of those pieces of art that no one should miss, anime fan or not be sure to watch it.
