So far, I really like this show.
To an extent, it's doing the Mad Men/costume drama thing of hooking me with the props, set design, and the basic premise, but instead of with cool old suits and interior design, with piles of books and documents and secret spy stuff. I like how this show realizes that computers showing fake
Hollywood OS animations and people staring at screens all day doesn't really make for compelling watching.
Also, it moves very slowly, but not at Tinker, Tailor, Soldier, Spy speed. Plus it seems to be getting into Illuminati territory.
