The story follows our favourite caped crusader as he is dragged through space and time when he tries to stop Gorilla Grodd from unleashing the power of his time machine on Gotham City. When Grodd's machine malfunctions it shoots Bruce Wayne, his foes and his friends in to the past and into Feudal Japan where, after two years have already past, Batman finds himself in a land ruled by clans. The Joker is at the center of this all, which leads to an epic battle between the two arch enemies, but however elsewhere Grood has other plans.
What ever you say about Batman Ninja, it is defiantly INTERESTING. The animated movie takes the anime style all the way. It feels like a modern anime but while this may sound like a good mix what we really get is an odd looking animated feature with a story that is, at points all over the place with no real sense, which is a real shame.
When it comes to character designs The Joker reminds me a little of the Final Fantasy villain Kefka, while the other villains just look like your basic anime or JRPG characters with little to really do with the plot apart from Grodd. It is odd seeing ninja versions of Robin and Nightwing but as I am not a follower of either the animated shorts or the Batman comics I am not sure about a few of the other characters, which can be a little confusing at times.
Overall Batman Ninja is just a run of the mill anime with a storyline that doesn't really mess with the canon of the series but gives you a re-imagining of the characters DC fans will love. Personally This wasn't really my cup of tea. While is am a huge anime fan I wasn't really into the style of the animation used, but it is one of those animated features you really should check out just so you can experience it.
