Superjail! is one of the few outstanding pieces of animation to come from the [adult swim] network in the last few years. This DVD is contains the 10 episodes from the first series (a second is planned) as well as a few extras: the pilot; animatics and a music video for the very catchy title theme.
The show revolves around a indescribably large prison, run by an exuberant Warden who is half Gene Wilder's Willy Wonka and half insane. The supporting characters include a trans-gender prison guard Alice, a tightly wound accountant Jared, a mass murdering robot Killbot, and a variety of uncouth inmates who take the stereotype criminal mind to an extreme by murdering each other at the drop of a hat. Each episode is roughly 10 minutes long and punctuated by a spectacular riot scene of some kind. The hallmark of the series is excessive violence and dark humour, but the show will often take a psychedelic turn either explicitly (episode Don't Be a Negaton), or by gently bending the laws of space and time in each episode with a pair of unexplained characters called "the Twins" who act as a foil to the Warden's plans.
Where the show really stands out is the animation (all done using flash), which is often so complex and imaginative that you can't possibly appreciate it all in one sitting, every scene is filled with background jokes or detail that put shows with larger budgets to shame. The fact that the title sequence in each episode is unique typifies the attention that goes into every 10 minutes. To a certain extent this focus makes the plotting or dialogue seem weak in some instances, but that is a minor negative compared with the rest of the show. It's also hilarious, but that goes without saying.
