Excerpt: CAUTION!Contains Spoilers!!! Tony Stark ( Robert Downey Jr.) seeks revenge to a terrorist, named The Mandarin ( Sir Ben Kingsley). And that's it that's the whole plot. I have heard very good things about the finale of the Iron Man trilogy and when I watched it, I was just completely disappointed. The movie begins strong Tony Stark in Switserland, 1999 where he meets Yinsen for the first time and Aldrich Killian(Guy Pearce), the director of a firm named "AIM".
