Interesting, but controversial.
First of all sorry for my english, I'm from abroad.
Second of all - It is the kind of animation I've been looking for. Something with a meaning, something that may trust you some kind of purpose, but only if you enough brains to understand it.
At first I tought it was some kind of abstract, meaningless and another full of bullshit noir animation that fills up NG to its tops.
But by the third time I watched it, I was finally able to understand the pain of the character.

How do you explain that?
