I just finished all 8 episodes of Fallout. I loved pretty much every minute of that show. I'm a huge Walton Goggins fan and the entire cast was excellent. I love shows like this, kind of reminded me of Severance, and Silo in some ways. I knew of the games but never really got into them. I can confidently say even if you haven't played the games and you enjoy a good sci-fi "evil corporation" type show you will enjoy this. Highly recommended.
Also, I just watched the first episode of Shogun.......WOW!!! So many great shows right now.
