It felt appropriate that Sofia Coppola's upcoming "The Bling Ring" had the last trailer before Harmony Korine's OMG-what-was-that "Spring Breakers." Korine's film aims, I think, for the unexpected truthfulness of Coppola's great "Somewhere," teasing out the layers of humanity in four co-eds who steal their professor's car and rob a diner at gunpoint to get the money to get down to Florida for Spring Break. (Selena Gomez, charming in 2011's "Monte Carlo," continues to show promise as Faith, the most introspective and godfearing of the girls.)
