Won’t Back Down

(PG) ★★☆☆☆

In this hyperbolic statement on the dismal state of public education in this country, Maggie Gyllenhaal plays a single mother who takes more than a passing interest in her daughter’s flailing education. Nona (Viola Davis) plays a teacher at her school, who is coping with a divorce and her own son’s learning challenges. It isn’t a badly made film, and it makes some vaguely salient points about education, but most of the film is overplayed and misses the mark. Once a movie sinks to that kind of hyperbole, not even Davis can salvage it.
