Just got done watching the first three episodes. So far the show reminds me of a cross between Firefly (peacekeepers seem a lot like the Alliance), Doctor Who, and Andromeda.
The pilot episode was pretty good. Interesting idea to have someone from our time end up in that type of situation far from home. The next two episodes on the ET encounter on the farm planet and the space bugs were at least serviceable.
It looks like I'll need to watch a couple more episodes to really get an impression of the show.
