I just found this show yesterday. It's a fan production, but don't hold that against it. I'm only an episode and a half in, but so far the writing's fairly solid, the plot moves at a brisk pace, and the production is top notch.
And it's so nice to see a "Star Wars" entertainment property, even a fan-made one, that's not about the Jedi.
