Not every space show is here for a long time. Some of them are just here for a good time – or in this case, only a single season.
There's an argument to be made that one season is not enough to determine a series' worth, since everyone is still trying to figure things out in real time. Having said that, would you rather the show get in and out in one piece, or drag its feet into the pit of "bore-me-to-death" like "The Walking Dead" (which was like watching actual dead people walk by the seventh season) or "How I Met Your Mother" (which made no one care how they met by the end)?
