Hana Barbara has an iconic style. It's kind of offensive to use that as an example of "crappy" animation. That's like saying Jackson Pollock's "crappy," slapdash paintings could never compare to the intricate detail of the Mona Lisa.

HB does have a very iconic style, but that style was deliberately chosen to make it easier to get away with low-quality animation techniques [1][2]. The HB shop needed to run on a shoe-string budget, and they had to cut corners wherever they could.

Now, it works because of the HB cartoons' light-hearted style and premises, but would seem tacky and ridiculous for a film or episode attempting something grander (i.e. a feature film like The Little Mermaid or Toy Story).

[1] For example, many HB characters don't have necks, or have extremely thick necklaces or collars where a neck would normally be. This allows you to swap out head and face animations with much greater freedom, and makes it harder to detect camera errors when the head and the body don't quite line up correctly. Is that bad? Not necessarily, but if you rely on too many of these tricks you end up painting yourself into a corner.

[2] Also, some HB characters don't even walk correctly. Their torsos and upper bodies stay perfectly motionless while their legs flail about beneath them. It looks cute and storybook-like in certain applications, but completely ridiculous in most others.
