Isn't it ironic that the world in the game that everyone hated, Atlantica was the only one that was actually closest to actually being Disney movie-esque? It had songs, it followed its original film's plot the closest(to the point of totally creating a gigantic plot hole considering it basically rectonned the first game's involvement with the world)...I mean wow. The only thing that kind of ruined it was that all of its gameplay was the song segments with nothing else to do and that some of its songs were crappy new ones.
Looking back on that, I kinda wish all the worlds were kind of like that(with their action/adventure gameplay segments kept intact as well as not getting any new songs either). It'd probably turn away all the douchey fans from the series who can't enjoy having a good laugh at that direction taken too.
