There's a tremendous amount of fun to be had in Kung Fu Panda, a superb crowd-pleaser with some of the greatest action I've seen of any movie. The filmmakers' taste however varies from mine; I wouldn't have chosen animals, some of which are simply a result of eccentricity, and which I suspect to have been deliberate.
On a third viewing, I still find the action impressive, but would not go as far as among the greatest. The lead character tends to be annoying, partly because he's used to legitimize lying (which is way too common in movies), and partly due to the slapstick humor. He also survives way too much physical pounding, and without a scratch. The movie is also shallow.
