After watching the 1st few episodes i wasn't sure if this anime would be interesting. Shabby Graphics, Lame Storyline, and Underdeveloped Characters were some of the issues i had.
But for some reason i decided to stick with it. And it was probably due to the Story. 12 Kingdoms delivers unexpected suprices from time to time such as killing off characters, Changing character development and other plot twists. And through this wonderful story telling it keeps you glued to the TV.
If you are a fan of fantasy stories then this is the anime for you. It might have a slow start to it but slowly but surely it grows on you. One thing about this anime is that as time goes by all aspects to it (such as story, animation and character development) seem to improve. And that perhaps is this animes best selling point.
