actually, the animation's great. think of it like Gainax's Gurren Lagann animation. It looked great when everythings are moving. But the moment you pause the move frame and look at them one by one they become crap like this.
Action scenes are pretty great imho. The plot however, a little silly. But hey, even the original kite didn't have a good story. It's mostly the style that got it the classic status.
