Just read DC Comic's Justice League of America: Salvation Run, and I think it's one of DC's best, or at the very least a must-read.

The basic premise of this is that, seeing as how more and more supervillains are overrunning the world, the government decides to set up a sort of Prison Planet - another world deep in space and far away from Earth. Captured supervillains are deported to this Prison Planet via Boom Tube (teleportation machines), and left alone to "start a new life" apart from civilization as we know it.

So, a bunch of murderers, psychopaths, egomaniacs, lowlifes, together on a wild and dangerous planet. You can imagine what this band of backstabbing villains will do to each other...the thing is, the creative team doesn't leave much to your imagination. I was surprised at the sheer darkness and savage morbidity of this story (faint of heart be warned), but that's part of what distinguishes Salvation Run from the rest. It's becoming more and more cliche to make villains more sympathetic to the audience, but writers Bill Willingham and Matt Sturges play these villains straight. These are evil people, through and through, and the creative team doesn't make any attempt to euphemize their nature.

In short, this is basically a version of Lord of the Flies...except these guys' fall from humanity has already occurred and there are no Piggys to prevent them from degenerating further. A frightening but believable tribute to the villains of the DC universe, Salvation Run is definitely something that even non-DC fans should give a read.
