Sharon Morrill should draw comfort from this.
Dan Kois rhapsodizes about the artistic quality and the lilting story notes of some recent sequels to older Disney classics:
[H]ave you ever actually watched one of Disney's DVD sequels? If you're expecting half-assed hack-work, you're in for a surprise. Lady and the Tramp II (2001), Bambi II (2006), and Cinderella III (2007), to take three recent examples, are certainly not perfect, but they're worthy successors to the originals, carrying the well-worn stories forward with care and charm. What's more, the movies tell their stories in the classic animation mode, using hand-drawn images, winning songs, and an energetic but not hyperactive style that has entertained children since Snow White and the Seven Dwarves.
I haven't seen any of the films listed above, but I've walked often enough through the studio where they were being crafted, and I can tell you that what Mr. Kois says about the care taken with layout, characters and the quality of drawings is true. Disney spent one hell of a lot of time and expense getting the films to look good, as the clips that I've seen certainly do.
I spent a couple of afternoons with background artist Bob Schaefer, who walked me through the backgrounds he was doing for Lady and the Tramp II, and though they were created with Photo Shop rather than paint, they were (are) gorgeous. And Bob went down to the Disney Australia studio (since shuttered) to make sure the crew down there got the backgrounds just right.
And I thought art director Carol Police did a great job on the art direction I saw on Bambi II.
How were the stories of these films? I don't really have much of a clue, since I haven't seen them, although a DisneyToons staffer who worked on Little Mermaid III told me: "The film is a prequel, and I thought they did a great job of tying things together from the original movie. It's a cute movie."
You want a review of Bambi III, Cinderella III, and Lady and the Tramp II, you'll have to delve into Dan Kois's article. The only Disney sequel I have a strong opinion about (because I've actually seen it) is Jungle Book II. The visuals on that feature I found to be top notch, the characters wonderfully drawn and the animation quite good, the backgrounds rich and colorful.
And the story of JB II? Sadly, it's a pale copy of the original and pretty thin gruel.
