** spoiler alert ** 
 Being someone who has no idea of recent history (what exactly do they teach at school nowadays?) I learned a lot about Russia. Combine that with a psychic spy story, and it's pretty interesting. I couldn't help but wonder - they were so cynical and skeptic of the Russian government, but when they get to the US it felt like they were blindly trusting them. Since they'd gone through hard times in Russia - and yeah, maybe life did get easier when they got to the US - but wouldn't they still feel the same way about their new country?
