The Bling Ring. It was a focused, small movie about a group of teenagers in LA who regularly burglarized celebrity homes, stealing high end luxury accessories and clothing.
The characters were all vapid and empty and two dimensional, but that coincided with their lame, materialistic, limited desires. The film was sort of an ethnography of excess, and it was beautifully filmed in a way that held my attention, even if none of the characters did.
Of note was the family of two of the girls, a new-age, Secret-devoted mother who was oblivious to and complicit with the shallow narcissism of her daughter.
