I actually started watching it for the first time probably about three weeks ago, and I really was impressed by the animation. Compared to the "action" cartoons we have now, there simply IS no comparison. The fights are fun to watch, the bodies have weight when they move, and like you said, the clothing moves dynamically. >>101195645
Given how much budget probably went into animating the characters themselves, are you really going to bitch about the backgrounds? It's an action cartoon, so logically the part of the show that looks the best should be the actiony parts, not the background.
