RE Animation
The difference between Japanese animation and American animation is very obvious. Personally I believe American traditonal animation is of far better quality.
Take an example of say an episode of Inuyasha versus an episode of Brandy and Mr Whiskers.
Both animations are storyboarded, and different scenes are done with different animators to ensure a speedy episode.
In a 15 minute episode of Disney's Brandy and Mr Whiskers, you see fluent animation throughout, most animation is similar and the complexity of the animation of even background characters and objects is unbelievable.
An episode of Inuyasha however, in order to save time and money creates the "illusion" of animation, by using various still shot's and tweening.
Examples are such as an establishing shot, you see a wide shot with various characters etc with dialogue in the background, but the shot is still, no animation just a scrolling character. Tweening is often used in action shot's to establish action without tedius animating. You can see this when inuyasha lunges at an opponent he is moving slightly against the background with the same looping animation going, such as his hair and clothes flowing.
Of course Japanese animation can be as top notch as disney animation, maybe more so. The attention of detail to every single character in the film "Steamboy" is astonishing, that film is a dream to study. The point is, every animation is going to have different styles. There are several animators working to try to get the animation exactly the same as each other. But if time and money is the essence, then animations can be excused for using cheap methods.
