>>9768697>87 show manages to have better backgrounds and animation tBetter backgrounds I'll give you(mainly because hand drawn backgrounds had soul) but if you think it has better animation, just rewatch it and wait until you get past season 2 where the episodes start getting grinded out. It picks up again for Red skies but its only bog standard action cartoon stuff. You might have nostalgia goggles for the 87 show.
That, and you might just plain like the art style of 87 more than 03. That isn't animation, though, but aesthetics.
