Blake Jenner and gritty 'Billy Boy' aim high with messy results

The grimy crime thriller “Billy Boy’s” original title — ”Juvenile” — better points to its energy, fueled by adolescent angst and fury, even if, in real life, its stars left behind underage status almost a decade ago. Written by and starring a bleached-blond Blake Jenner, “Billy Boy” is ambitious in its structure, style and editing, but the final product is disjointed and irritating.
