I picked up season one of the SyFy series Defiance a couple of weeks ago. I've watched a few episodes and I have to say I like it a lot. It reminds me of Firefly because it has a strong central male character but strong female characters around him as well. But more than that it has a Wild West feel about it, a town called Defiance needs a lawman and someone to help ordinary citizens (of a variety of alien species, known collectively as Votans, and humans) muster a defence force to protect the town from the Volge. There are lots of internal politics between the different Votan species and this is what makes it so interesting. I'm looking forwards to watching more episodes.
