Variety called the film a "heavy-handed inspirational drama" that "grossly oversimplifies the issue at hand." The site continued, "Barnz's disingenuous pot-stirrer plays to audiences' emotions rather than their intelligence, offering meaty roles for Maggie Gyllenhaal as a determined single mom, and Viola Davis as the good egg among a rotten batch of teachers, while reducing everyone else to cardboard characterizations. Absent high-profile champions, femme-centric pic could suffer from low attendance."
Roger Ebert of the Chicago Sun-Times rated the film 2 out of 4 stars, writing: "Both the lottery scene and the anti-union material seem to be fictionalized versions of material in the powerful documentary Waiting for Superman which covered similar material with infinitely greater depth."
Michael Medved liked the film, giving it three and a half stars (out of four) and calling it "... one of the better films of 2012."
