Critic Reviews from Rotten Tomatoes

"The endearing airborne-beagle effects help to offset the formula twists."
‑ Owen Gleiberman, Entertainment Weekly
"Whatever the intent, the result is unfit for humankind."
‑ Scott Tobias, AV Club
"Underdog as a film is not totally worthless. It's a winner with kids, as is anything with a talking dog."
‑ Kevin Carr, 7M Pictures
"While this idea may have been enough to happily fill 25 minutes, the film version fails to effectively stretch it out to feature-length."
‑ Saxon Bullock, Film4
"...an affable, sporadically entertaining piece of work that's ultimately undone by its emphasis on relentlessly silly elements..."
‑ David Nusair, Reel Film Reviews
"After a lovably dopey prologue culled from the TV cartoon, this live-action adaptation gets down to the business of entertaining tweens, earnestly and nonironically."
‑ Joshua Rothkopf, Time Out New York
"The lackluster story connects the clichés but leaves the characters isolated. Underdog may have been originally created to sell cereal for General Mills, but this latest incarnation couldn't sell Frisbees at a dog park."
‑ Jeannette Catsoulis, New York Times
"Underdog works best when spoofing superhero conventions, but the film goes to the dogs thanks to a drab story and frequent stabs at heartwarming bromides."
‑ Tim Grierson, Screendaily
"Call me a kid at heart, but Underdog is the cutest doggone fantasy."
‑ Urban Cinefile Critics, Urban Cinefile
"Despite the talent on show, there's little to distinguish this from any other bland family comedy."
‑ Anna Smith, Empire Magazine
"It's a harmless bore."
‑ Roger Moore, Orlando Sentinel
"Underdog is made for the Saturday morning TV crowd, and parents who lead their tykes to this adventure aren't likely to leave disappointed."
‑ Jack Mathews, New York Daily News
"The essential cartooniness of the plot and the gags works against the rather lame attempt to lather on a message about reconciliation between father and son."
‑ Steve Biodrowski, ESplatter
"At just over 80 minutes it feels not so much like a proper film as a piece of extended filler for slow afternoons on Disney's TV channels."
‑ James Rocarols, BBC.com
"An ill-conceived and often irritating bout of Children's film fare..."
‑ Felix Vasquez Jr., Cinema Crazed
