Barb, dear, this is the same studio that is giving us "Snow Dogs". I don't think they're really trying anymore. All of the creative guys (and girls) moved over to Pixar, for the most part.
That's all right, though. Now I can look a boycotting Southern Baptist in the eye and say that I don't watch Disney films...
Seriously, right now, with family films making a comeback and the black eyes the Mouse House has gotten over the past few years with some rather questionable ideas (and you though FOX Family was bad...), Eisner, et al, see these sequels as the quickest way into people's pocketbooks... er... HEARTS! Yeah, hearts...
Unfortunately for all involved, Disney is ripping the hearts out of real animation fans, the main ones who kept them afloat for so long, because they desperately need dinero... now. Even if no one sees this dreck in the theaters, they'll probably make back their 5-and-dime animation budgets back on the video release, and on Disney Channel, and Toon Disney, and ABC, and ABC Family... getting the picture yet?
It doesn't matter to Disney execs if the material's any good. They just need stuff to fill their catalogs and TV Channels.
And sequels are the easiest way to do that.
