OK, so when the first part of season 4 dropped, I remembered that, due to life happening and whatnot, I had never actually watched season 3.
So, I watched a recap of season 2 (since that seems SO LONG AGO now), tore through season 3, and just finished episode 7 of season 4.
THAT WAS PRETTY GOOD.
I loved the revelations in episode 7. Still curious to see how the expatriates get out of Mother Russia.
I only have one complaint about the season, which is Holy Shit at these episode lengths! I mean, they don't drag or anything, they aren't overly long per se, but they just aren't as convenient to my personal watching habits when they are that long. I wanted to watch seven TV episodes, not 7 movies.
