The 25 Best Adult Swim Series Of All Time, Ranked

"Superjail!" is set in an otherworldly maximum security prison for the universe's most dangerous criminals. The facility's incompetent staff members are the series' focus, with the Warden, a fun-loving and seemingly omnipotent being, at the heart of it all. The Warden is, at once, a shape-shifter, a tyrant, an excitable kid, a mischievous imp, and possibly some sort of god. He longs to incarcerate the entire world, and just might accomplish that terrifying, candy-colored dream. 

Known for its psychedelic art style, experimental storylines, and extreme violence, "Superjail!" isn't a show for every viewer. Even by Adult Swim standards, the series is extraordinarily violent: Many episodes end in gory climaxes that involve dozens of grisly deaths. The Warden isn't exactly filled with reverence for human life. However, the technical sophistication and ceaseless imagination of the series' hallucinatory visuals can't be denied, even if many viewers feel the need to watch them from between their fingers.
