Best two reviews:
1) HitFix - It's a feel-good story that raises cultural questions that the film doesn't seem terribly interested in answering, and it feels like an easy triple in the grand Disney tradition. (Rating: 75) Read Full Review >
2) The Hollywood Reporter - Credit a rock solid turn by lead Jon Hamm that doesn’t shy away from revealing a darker underbelly to his underdog character, as well as a keenly-observed script by Tom McCarthy and deft direction by Craig Gillespie for the rewarding changeup.

Worst two reviews:
7) The Wrap - This “based on a true story” underdog tale is infectiously determined to make you fall in love with it, like a mangy dog that plops its head in your lap and gazes adoringly at you until you scratch it behind the ears. Eventually, you give in and scratch. And then you wash your hands. (Rating: 50) Read Full Review >
8) The Dissolve - The only splash of cold water comes from Lake Bell as J.B.’s bohemian tenant, who pops his bubble of self-importance (and the film’s) whenever she gets the opportunity... her chemistry with Hamm, who gives his slickster all the dimension he can, offers a nice relief from the broad culture comedy and sentimental button-pushing.
