I Am Sam

What to say about Penn’s Rain Man-meets-Forrest Gump mentally challenged dad (garbed in the requisite zip-up jacket and high-waters), who must save his pixieish little girl from the clutches of a cruel social services system? He’s got a passel of adorably tic-filled (and similarly challenged) pals, a kooky neighbor (Dianne Wiest), and a hardass lawyer (Pfeiffer) who just might learn a little something from his idiot-savant wisdom. Oh, the word mawkish comes to mind.
