I didn't expect much from "Brand X," FX's new "talk show" starring British comedian Russell Brand, and yet I got even less. With his disheveled locks and quasi-bohemian dress, Brand is as much a personality as a performer, having managed to not only survive but leverage a medley of dysfunctions (including ADD, heroin addiction, alcoholism, bulimia, divorcing Katy Perry) to create an image of the bleary-eyed, often low-brow but sometimes surprisingly literate scapegrace.
