1. It's got the same themes as Battlestar Galactica

There haven't been many great TV shows about politics (besides The West Wing and the occasional episode of Spin City), and there's never been a great show about religion (sorry, Touched by an Angel, but no). Part of the fun of BSG was how it used the window-dressing of science fiction (starship battles, robot clones, funny space talk) to create a thinly veiled exploration of contemporary political and religious life. On Caprica, set 58 years before the events of BSG, the veil is even thinner. Although nominally about the invention of a race of robots called Cylons, Caprica is really a closely observed drama about a booming civilization on the brink of crisis.
