Anybody with a daughter can tell you The Little Mermaid is anything but forgotten.

If we're going to be pedantic here, lets at least attribute the continued success of Disney's vintage films to their appropriate source: Disney's relentless marketing.

That's not pedantic, that's just an unsubstantiated opinion.

I'd argue that Disney's animated works as a whole is much more culturally relevant than Hanna-Barbera's portfolio. But I do agree that quality of animation is not the deciding factor in that determination.
