Most of the Japanese studios do not blow their budget recklessly, while also having top notch animation on serious parts. Who the fuck cares if a character's mouth isn't wagging enough when they speak on unimportant events?
Note for idiots: Absolute fluidity does not make your animation good nor special. It's a matter of budget and style. Every animation can have fluid animation but not good style. Avatar has fluid animation but shitty colors, art, camera angles, a very dull style and design.
The reason why some people like anime is because it exploits its medium more than modern western cartoons. People like me like anime as an alternative to American live-action shit.
