I was in the midnight showing of this movie, which was sold out. People were riotous and loud during all of the previews (especially the new Twilight movie), but when this movie began it only took a few minutes to shut everyone up, and to keep them quiet aside from applause. I definitely enjoyed the film and will place it very near to the first one in my heart. It stays true-to-genre as a 2nd (in a likely trilogy of) superhero movie(s), and a sequel to Iron Man. And as people have said before, make sure you stay until the end of the credits. :)
