I saw it last night, I agree with almost every word of Bob's spoiler free review, which was also surprisingly light on political commentary. What I get from the Marvel Movies when they try to tackle real-world politics is that they take an already-prevalent paranoid conspiracy theory, and make a plot out of that (ex: Iron Man 3's plot twist and now Captain America: Winter Soldier's), and it is a doozy! I've been watching Agents of S.H.I.E.L.D. since day 1, and I gots ta see how they follow up!
Oh, and of course, stay through the end credits! You won't want to miss them.
