All the storytelling is done mostly through exposition, meaning the animation can be as simple as they can get away with.With the altered artstyle used for this half of the Pain battle, though, much, MUCH more thought was given to how the animation would look as a *whole*. Every individual frame is done so that they're as consistent as possible with the previous frame because it requires the least forethought and results in an animation without too much character.
NARUTO VS PAIN ENGLISH DUB TV
The ordinary artstyle is done with the sense that it's a tv show, that commercials can interrupt at certain points or that people may pause their media devices. It's meant to be viewed as a whole, and it does a hell of a good job of communicating to the viewer that *something is different*.Another thing that a lot of people seem to think is that the animation is lazy.
This transition is mirrored perfectly in the messy, exaggerated, over-the-top animation we see from then on as Pain too begins to show more emotion than he's ever even hinted at before.The animation isn't meant to be realistic, it isn't meant to be scrutinized frame-by-frame. Once Hinata is killed in front of Naruto, though, he loses all sense of sanity and rationality and embraces the pure animalistic emotions he feels in that moment, ultimately channeling the Nine-tails. Even during the previous scenes between Naruto and Pain, the artstyle is pretty consistent with a normal fight. People hating on the animation in this scene really don't understand what it stands for most of the show's animation is very structured clear outlines, consistent shaping of objects and characters with minimal distortion, basically exactly what you'd expect in normal animation.
