Review: In Cinemax's 'Banshee,' there's little justice to be found

An ex-con with an assumed identity becomes the sheriff of a small town in 'Banshee,' a violent Cinemax drama that doesn't have anything new to offer.

There's a new sheriff in town, only he isn't really a sheriff, he's a recently released ex-con fully rigged with antihero requisites, including killer instincts and his own twisty-but-true moral code.
