The landscapes/scenery are some of the best done in any animated movie ever... but yeah, the rest is garbage...
I think that was part of the problem. The photo-realistic landscapes with the overly-cartoony dinosaurs was just jarring. (Admittedly, the lackluster story was a larger part of the problem.)
On subject for this thread: I'm glad I got to see this when we went to WDW in October. It was a nice show and very well done by the musicians.
