Just got home, as I went out for some late night entertainment.
I liked it a lot. Me only beef (which I have with a lot of "action" movies) is that they CGI in so much action that sometimes it can hard to see exactly WTF is going on. Without putting in spoilers, the section at the expo was kinda hard to pin onto because so many things were moving and exploding simultaneously.
Other good things:
SHIELD(s)
Tom Morello contributed a lot to the score
I am not a Scarlett Johansen fan at all, but she makes a pretty good Black Widow and the curves do great with that jump suit.
Some of the scenes are just really funny, like the Senate Hearings.
I was kinda so-so on Nick Fury. They played him a
bit to wise-crackin' for my taste but he definitely gets the job done and is a good addition to the movie.
(Spoiler Alert)
Oh and stick around to the end. It was so good that I had to get hammered....
