New Fantasyland was not meant to be spectacular though. Whereas Magic Kingdom needed more land to spread out the crowds, Animal Kingdom needs rides to actually boost its attendance and get rid of the 'half day park' stigma. Same goes for DHS.
I think it's fair to say that Imagineers are still able to deliver in regards of creativity. Carsland is the perfect expample of the company actually making an effort to get something right.
Carsland or even DisneySea are no guarantee that Avatarland is going to be Disney at its best, but I don't think New Fantasyland and Avatarland should be compared as they both have different purposes.
