I am usually hesitant to see a movie on opening night, but I went for this one, I had been looking forward to it for a long time. My friends and I did not get to sit together, very crowded theater, but it was sure fun to compare notes afterwards. The entire audience was spellbound. Great casting. I knew there would be conflict between any character and Iron Man, but the level of some of the other interactions was just WOW. We saw it in IMAX 3D and I definitely recommend it.
