Todd McCarthy of Variety gave the film a negative review, saying "As directed by David Bowers and Sam Fell, first-time feature helmers with long-term Aardman affiliations, the film boasts undeniably smart and eye-catching qualities that are significantly diluted by the relentlessly frantic and overbearing behavior of most characters; someone is always loudly imposing himself upon another, to diminishing returns of enjoyment. " Owen Gleiberman of Entertainment Weekly gave the film a B+, saying "Flushed Away lacks the action-contraption dottiness of a Wallace and Gromit adventure, but it hits its own sweet spot of demented delight. " James Berardinelli of ReelViews gave the film three out of four stars, saying "It's better than 90% of the animated fare of the last few years. It's refreshing not to have to qualify the movie's appeal by appending the words, 'for the kids'. " Jan Stuart of Newsday gave the film two out of four stars, saying "Despite the efforts of five writers and Aardman's trademark puppets, with their malleable eyebrows and cheeks bulging like those of a mumps sufferer, none of these characters are particularly endearing. " Ann Hornaday of The Washington Post gave the film a positive review, saying "Flushed Away, Aardman's first computer-generated cartoon, does away with the clay but leaves the craft and emotion intact, resulting in a film that earns its place among the Aardman classics. " Peter Hartlaub of the San Francisco Chronicle gave the film three out of four stars, saying "The short attention spans of directors David Bowers and Sam Fell are mostly forgivable because the movie is filled with so many entertaining characters.
