I really liked the animation and the action sequences and I thought it was cool how it kind of turned into a creature feature towards the end, but it wasn't as good as I was hoping it would be either and a part of me does wish they had just stuck to the real story behind the character.
I'm sure it would have been far more interesting than the standard anime fare that they gave us here anyways, especially for people like me who have never even heard of Yasuke.
