This is a great adaptation of the comic book. The animation mirrors the art of the book. The acting is good, especially Jeremy Sisto's interesting take on Batman. What a voice! Yet, the film felt a bit too short. If you have read the book, it takes its time building up the story and the characters, so that at the climax we actually feel for them. The book produced a lot of emotion for me. The film just didn't quite achieve that feeling, and that is a shame. If the producers had just allowed more time for the story, this could have been a truly great film -- a classic. That's why I'm giving it 4 stars.
It is a lot (a lot) better than the other animated comic book adaptations out there though. Worth purchasing. If only the Justice League animated series had taken some notes from this work.
