Hunchback was a strange choice of a Disney movie to begin with.
It really seemed that in that period EVERYTHING got a sequel except for things that should have had sequels. Hercules 2 never happened... and the rumor was they were going to use the original plot of the Hercules movie (the one we didn't see all about the Trojan Wars), but instead just gave us the first 3 episodes of the cartoon edited together.
I will say it was strange they made a sequel (and animated series) of Emperor's New Groove, considering they treated it so shabbily when it was first released. That one was pretty good too, actually.
Now, what I wanna know is what strange exception the Tinkerbelle movies keep getting. I know the first one was far too into production to cancel completely (they just rewrote the first one before it was finished), but they keep having follow ups to them. These are based on Italian comics, which leads me to ask, why not give Donald Duck's Italian alteregos some DTV's? Secret Agent, caped vigilante... The third and final Chris Nolan Batman movie's coming out this summer... it would have been the perfect time to capitalize on it with a Duck Avenger DTV project. We haven't had the comics for over a year or two. Those were really good.
