This movie was good, with the only purpose of entertaining kids and grown up people too. The adaptation from the cartoon was really good and the plot was convincing and very well developed although the story has some flaws, for example, Sweet Polly was a poodle in the cartoon not a cocker spaniel. The cast was good very decent acting from everyone, Jason Lee as the voice of Underdog was very good as well as Amy Adams as Sweet Polly. James Belushi performance was good, very funny and the best one of all in my opinion was Patrick Warburton as Dr. Barsinister. In conclusion, a typical family movie, very enjoyable and entertaining.
