After an accident in the mysterious lab of maniacal scientist Dr. Simon Barsinister (Peter Dinklage), an ordinary beagle unexpectedly finds himself endowed with unimaginable powers and the ability to speak. Armed with a fetching superhero costume, Underdog (voiced by Jason Lee) vows to protect the beleaguered citizens of Capitol City and, in particular, one beautiful spaniel named Polly Purebred (voiced by Amy Adams). When a sinister plot by Barsinister and his overgrown henchman Cad (Patrick Warburton) threatens to destroy Capitol City, only Underdog can save the day.
I liked this film! Good, simple entertainment, plenty of jokes, nicely paced and not over-long. Arguably this is a dog's breakfast that borrows from Beethoven, K9 and so on but the effect on me was fond reference rather than plagaristic. I noticed enough loose ends were weaved into the ending to leave the door open for sequels; I'm not sure it's that strong but worth seeing anyway. Give the dog a bone!
