America F**K Ya!
Sorry, couldn't resist. All the time I was waiting to see Captain America: The First Avenger the "theme song" from Team America: World Police kept going through my head. Every now and then I'd say the above line out loud and have it echoed by my friend Gary, or even just say "America!" and he'd supply the rest.
The movie was good, on par with Thor with the level of writing and special effects. The humor was well placed and didn't feel forced, the actors hit the right notes at the right time and were even able to subtly put forth emotions that might have been missed or glossed over in other superhero movies.
But in the end, this is a superhero movie so go into it with eyes wide open. It's a good one, but don't expect Shakespeare. It ties in very nicely to the rest of the Marvel movies leading up The Avengers, and make sure you stay till then end of the credits for a little treat of what's coming out next year.
