I really like Black & White, musicals and animation films.
This is the Bible of backgrounds.
So much detail in every corner, the grafittis, posters, stores, apartments, etc...
If someone has an assignment of backgrounds, I totally would recommend this.
The story for the other part, it's fine, very dark in the second act. Feels a lot like "Akira", but instead of one character, this one has the brotherhood of two orphan's.
