Like the title says. Go see the movie. Whoamg. It is basically... amazing.
It is the complete package. You have joy, comedy, drama, action (a LOT of action).... Eye candy all around (from the dirty pirate hooker Scarlett Johansson) to Cobie Smulders (of How I Met Your Mother fame) to Cap'n America and THOR.
It'll make you laugh, it'll make you cry, it'll make you cry from laughter. You'll hoot and holler. You'll be on the edge of your seat.
Seriously. It's freaking amazing.
Stark's one-liners, Captain America's wholesome 1940s American-ness, Nick Fury's bad-assery, and Thor's wielding of Mjolnir....
With this movie, The Dark Knight Rises, and The Hobbit coming out in 2012, there is simply no reason for Hollywood to make more movies.
Also, keep your spoilers out of here.
But, as a note, if you see it, STAY FOR ALL THE CREDITS! There are TWO post-movie scenes in the American version. So, stick around for the first one, settle in, talk about how epic that was, and then stay for the last one after all the credits roll.
As a final note, recasting Mark Ruffalo as Bruce Banner was pretty great. Still frustrating that Chris Evans plays both Captain America and Johnny Storm in the same Marvel universe, but oh well...
Seriously. Go see it. Right now. You won't regret it. Unless you haven't seen like, Iron Man, Thor, Captain America, and so on. Then watch all of those. Then go see it.
