Having Pixar’s John Lasseter in the driver’s seat at Disney animation is certainly having an effect, as this CGI comedy about a TV star pooch who must come to terms with the fact that he is not a superdog, as he has been led to believe, is light and funny and charming (and even a bit thrilling) enough to make its messages go down easy. And, while above-the-marquee stars John Travolta and Miley Cyrus are certainly competent, it is the unknown Mark Walton and his hilarious fanboy hamster character who is truly memorable.
