This is just one in a series of animated adaptations of famous comic books. Whilst I loved what Nolan did with his movies (the first two anyway), nothing captures the true spirit of Batman like these animations from Warner Animations.
This film is based on Frank Miller's Batman: Year One (which as you may be able to tell was also a heavy source of inspiration for Batman Begins). It manages to stay true to the comic book and also be entertaining as a movie and whilst this is not my personal favourite of these animated movies out at the moment, it is certainly deserving of five stars.
For anyone who is willing to look pas the fact that this is animated and get into the spirit of a good story well told then this is really a great film to watch. For Batman fans this is a must and for those who have already seen this and are wondering what to watch next I would recommend Batman Under the Red Hood.
