The animation is not polished, it's true, but American Animation had yet to improve to the levels of the 2000s .
Oh, that is so very, very untrue.
Prince Valiant and
Phantom 2040 looked terrible in comparison to the other animated shows that were on
at the same time, such as
Batman: The Animated Series and
Gargoyles (or just about anything from Warner Bros. and Disney). Even
X-Men and the early seasons of
The Simpsons, from the generally execrable Akom Studios, didn't look as sloppy and crude as the animation in
Valiant and
Phantom -- although the syndicated season of
ExoSquad, which was also Akom, looked nearly as bad. There was a wide range of animation qualities in '90s television, ranging from near-feature-quality to utterly awful. And the Hearst shows were just about at the bottom of the barrel.
I do still think they tried to do some unusual angles and persepctives, and some of the design elements were really forward thinking...stuff not seen on run of the mill future based American cartoons, or often in live action either.
Sure, the problem wasn't with the designs (aside from my distaste for Peter Chung's character design style) but with the execution. The way US animation has worked for the past 2-3 decades is that the designs, storyboards, layouts, and sometimes key character poses are done by the production team in America, and then it's shipped (or, these days, e-mailed) overseas to an Asian studio that does the actual frame-by-frame animation, which is then shipped back to the US for editing and post-production -- and sent back for reshoots in the event of errors, which is far more easily done today than when everything had to be physically shipped. So there's not necessarily a correlation between the quality of the design and composition and the quality of the final animation. Depending on which animation studio you end up with, they can elevate the material or drag it down. There was nothing wrong with the US production of
Valiant and
Phantom, but the animation itself was of far lower quality than everything else.
