Just finished it.

I thought it was good, but not great. The initial episodes were stellar, but as it got to the main arc of the story, that's where it faltered.

The final episode might be a letdown for you (or not), and depending on the success of the show, we should get Season 2.

Overall worth watching, great premise, brilliant acting performances all around, and you will grow to like the cast. The music score is amazing (thanks to Ramin Djawadi again, very GoT).

At best, an 8/10. Check it out if you're a fan of sci-fi / thriller shows.
