IMO this era made movies rivaling some of the very best they've ever put out overall but it's certainly biased that I was a kid during those years and automatically like them the most. They've got the classic memorable songs and soundtracks (that the CGI/Pixar movies seem to have lost) and some of the most amazing animation ever seen in....well, history. They incorporated CGI in ways that simply helped the traditional animations come more to life. They never really overdid it and that makes them more special. Plus the actual animators used to do some insane on-location research (Africa for LK, Paris for Hunchback) back in the day.
Sure, I've seen and enjoyed my fair share of Direct-to-DVD sequels (Aladdin ones mostly) but they never really add anything to the original in terms of depth or story, it's always just been to get well-liked characters in another situation cuz kids love that. Actually, now that I think about it, aren't kids the ones who should be asked about these sequels instead of adults assuming kids don't like 'em?
....or something.
