Sometimes, Hollywood fails in making a sequel that's just as good or better than an original film: not so with Iron Man 2! This movie is a complete success from the very beginning, containing exciting action scenes, invoking concern from us viewers, and making us laugh. The roles were well acted by everybody. Robert Downey Jr is an on screen delight...his method of acting is so much fun to watch. He has a charisma that many actors of today seriously lack. He took on the role of Tony Stark as if he was truly that man. He had perfect chemistry with everyone, and I was sorry to see the movie end. I haven't seen many of RDJ's older movies, but as far as I'm concerned, I plan to see everything he makes from now on!
