I'd say a good 8/10
If you liked Battlestar Galactica, Star Trek, Firefly, or any of the spacy traveling crew shows, you're gonna enjoy it. The way it feels is the way I expect people in the 70s did watching Star Trek. The technology feels so realistic and attainable yet a century ahead of our own technology. I'm not saying it's the best space show out there, but it's definitely in my top 5.
More than worth a watch, go at least three episodes until it really picks up. Can't wait for season 2!
