The show features a cast of eccentric and colorful characters, including the ruthless Warden, his loyal assistant, the sadistic Alice, and the flamboyant, cross-dressing Doctor. The series is known for its surreal and dark humor, as well as its graphic violence and sexual content.

Each episode of Superjail! typically features several interwoven storylines that take place within and around the prison, often involving the various inmates and their attempts to escape, outwit, or manipulate each other, as well as the prison staff. The show's animation style is highly stylized and frequently incorporates psychedelic imagery, rapid cuts, and surreal transitions, giving it a frenetic and disorienting feel.

Superjail! has been praised for its innovative animation and its willingness to push boundaries with its edgy humor and graphic content, although it has also been criticized for being excessively violent and vulgar. The series has developed a cult following among adult audiences and has been compared to other animated shows such as Adult Swim's The Venture Bros. and Aqua Teen Hunger Force.
