You've got to see this movie! I caught a midnight showing to avoid the crowds and it was extremely worth it.
I'd been waiting on this for years and wasn't disapointed. Years ago, I was critic al of Robert Downey Jr. because it angered me that someone so talented would throw their life away with drugs and drama. This was the perfect role for him because the character he played (Tony Stark) synonymously lived a carefree life only to come to a crossroads where a decision had to be made. That's when the big epiphany happened, giving him reasons to live/work towards something higher.
Marvel continues to successfully re-invent itself on film! This is yet another franchise that will have a strong following.
