I've been impressed with this show, what little I've seen of it. At any rate... I need some filling in: I've got an incomplete understanding of the setting. I know the captain is out of his element - but recently picked up that he's from a different time? What's the deal with that? Is the ship from his time as well? The "Commonwealth," what is (was) it? To me, it sounds like a defunct "Federation of Planets" based around Earth at one point. And only if this doesn't take too long: Where'd his mix-matched crew get assembled from? Thanks.
