While it might not seem like the perfect setting for a story, prison is the subject of comedies, dramas, and even reality tv in a variety of series, and though there are vast differences among them, the best prison shows to air all feature compelling stories and multifaceted characters. A lot of prison-centric shows are dramas, and not for audiences seeking lighter fare. That's because for a series to be set in a prison long-term, the characters have dark reasons for being incarcerated, and sometimes have to do violent things to maintain their status. That's especially seen in successful shows like Wentworth and Oz.
