The premise is awesome - Keri Russell is terrifyingly cold, Matthew Rhys is very believable as a husband who is tired of his sacrifice, and tension is literally built into every scene as a result of the CIA agent living next door. Noah Emmerich was great as well. Excited to see where they take his investigation. Much like Hank Schrader on Breaking Bad, I could easily see the audience rooting for him by the season finale.
I only had a few gripes - 1) Kerri Russel's Russian accent and 2) Phillip's revenge attack on the brute/pedophile from the mall, which felt a little bit too action movie forced. I realize he's a spy, but I don't think he'd search out unnecessary danger and he probably wouldn't be capable of taking that guy down so thoroughly. I prefer the idea that his wife is the badass, while he's the brains.
