We marathoned it over the weekend. Full spoiler below.

Spoiler:

I think overall it was so-so. I hated that Doug came back, and feel like the show would have been improved with him just dying and the girl never being heard from again. I felt like Francis sucked super hard too. Idk what thats about, though I'm usually slow with understanding whats going on. Anyway, given how badass he was in seasons 1 and 2, I'm really surprised he let Petrov own him so many times, and that Francis couldnt really do anything about it. Like, I expected Francis to somehow blackmail/pressure Russia into falling in line, but instead we just have him always being under Petrov's thumb. Lame. Real-ish I guess, but lame. Claire drove me crazy too.
