Finally got to see it today.. really, really liked it.
Not much to say that hasn't been said already.. but the action was done really well, Evans held his own, Scarlett delivered, I could have used more Anthony Mackie but he was solid as well. The material definitely felt relevant and important for today's audience, the cost of freedom, monitoring and going after threats before they're even threats, etc. really loved the storyline. Winter Soldier was a great villain as well. I know it's been discussed, but one of the faults of Marvel Studios has been weak or non-memorable villains outside of Loki. Winter Soldier was impressive and him remembering Cap managed not to be cheesy or overly sentimental.
Loved the Abed cameo
Definitely #2 behind Iron Man for best non-Avengers Marvel film.
