Dad (Dennis Quaid) is a dyed-in-the-wool, midwestern corn farmer doing anything he can to survive in the world of genetically modified crops. But sonny boy (Zac Efron) just wants to be a NASCAR driver. If that sounds like a contrived plotline, you're correct. But up-and-coming indie director Ramin Bahrani (Chop Shop, Goodbye Solo) wrings some great performances from his stars, resulting in a surprisingly sincere melodrama about the modern farming industry, small-town entrapment and father-son dynamics.
