In my opinion recent cartoons are too heavily edited, even when the editing is done by the cartoonist/creator himself. Now that editing is easy and can can be done on a laptop every shot in a cartoon is edited and re-edited til it's considered perfect. That may enhance the filmic quality but it diminishes the sense of preformance and risk. Some cartoons give me a case of "smoothitis."
Easy edits also tend to increase the number of cuts. We all know films that benefited from frequent cuts but I bet I can point to an equal number that were hurt by it. Fred Astaire used to cut his dance scenes as little as possible and it's easy to see why. It's the same reason that magicians on screen resist too many cuts. The audience assumes that the cuts cover up mistakes or chicannery. They think cuts make the performance easier, too easy in fact, and they paid to see somebody do something that's difficult.
On a related subject, I'll add that quirky motion sometimes adds to the appeal of a scene. Some of the jerky stop-motion on Harryhausen's best scenes (I emphasize the words "some" and "best") actually improved the fantasy. It gave the monsters an unreal, unearthly style of movement that fit the story. Cartoon animation works the same way. Nobody wants jerky animation but we want to see some near misses, some last-minute saves, some cheats that give us an idea of how difficult it is to move this stuff. We want to see a first-rate animator's struggle. Hemingway wrote that nobody can appreciate a good bullfight til they've seen a bad one. That applies to what we do. Let's stop being so slick!
