The energy level is very high, as is the humour quotient, as the story ricochets all over the place, filling the screen with witty pop culture references, action-packed set pieces and lots of knowing self-parody (such as the admission that the story makes no logical sense, but never mind). As a result, even the grown-ups will chuckle happily as the manic film rushes by. Spade pretty much plays himself as Kuzco, with a constant stream of dry jokes and acerbic asides that sit nicely in contrast with Goodman's more gentle-hearted character. The Major Life Lesson is refreshingly low-key. There aren't any songs, so to speak, besides a few tunes crooned by the court jester (voiced by Tom Jones, of all people!) and the closing theme by Sting. There are rather a lot of inspired sight gags, especially the "cruel" fate awaiting Yzma. And there's not much else to say, really, about this diverting, silly bit of fun.
