I was very happy with it. The movie was true to the character from beginning to end.And Robert Downey Jr. was perfect as Tony Stark, and not just because they have shared similar vices: It was shocking to me, how much Downey's sense of humor matches so perfectly with Stark's. And even when showing us a serious, determined Tony Stark, Downey hit the nail right on the head. I can't imagine anyone else playing this part. Or doing this well with it. Good for him.
Iron Man's origin story is so simple, so straight-forward, and I was happy to see that they changed very little of it. If it ain't broke, you know. And the Iron Man armor! YES! It was perfect! And every level of it, from the apparatus Tony uses to put the armor on, the boot rockets, the repulsor rays...all of it, perfect, and right in tune with the source material. When Iron Man takes on the terrorists attacking the village, I got a very rare shudder of excitement, the same excitement I felt when Wolverine first plunged his claws into a guy in X2, or the first time I saw Spider-Man swinging from his webs in the first movie. It was the excitement of seeing something I've imagined a thousand times in my mind, big as life on a movie screen, and better than it ever was in my head.
And the most exciting part of the movie isn't even really a part of the movie itself. That after credit sequence is a watershed moment in comic book movies. The thought that al Marvel movies will be connected from here on out? And that this interconnecting continues with The new Hulk movie in June? My mind is blown. I can't wait to see how they do it.
