Went to see it in 3D today, and thought it was fantastic. It's a film with a lot of heart, but it manages to avoid alienating non-Americans by not overdoing the patriotism. Evans is pitch perfect in the role, and his final line to Fury about having a date was about as perfectly in character as it gets. Sterling performances from pretty much everyone involved, and the story was spot on.
The after credit scene was a nice touch, and the teaser for The Avengers that followed it got me nicely psyched for that film, so I can't bloody wait for next summer.
I also got to see trailers for Skyrim and Battlefield 3 that I hadn't seen before, so that was cool.
Off topic, but after seeing the trailer, this Super 8 film comes across like an American remake of Attack the Block.
