Hey Parkhoppers,
Snappy Squash and Stretch is a style, not a cost effective way of creating animation...otherwise every TV cartoon would be doing that style. It takes just as much effort to do it as say the Glen Keane style of animation used in Little Mermaid or Tangled (gentle use of squash and stretch) or the heavy reference/realistic style that is used in Frozen. If you look at the Hotel Transylvania films that Sony puts out or the Madagascar films by DWA...that is snappy squash and stretch. It kinda takes more time for snappy squash and stretch as you have to key it all by hand as shooting reference can't be done cause the movements are so fast and exaggerated...
So while I agree, back in the Golden Age of Disney animation, all of it was polished, and now not all of it is...but there is a difference between the style of animation and quality. But specifically on the Mickey Mouse Show, it seems what you don't like is what the show is doing on purpose...but, is the animation as polished as it could be? No, it's a TV show afterall. Is it poor quality, well, I guess that is where we disagree
