Though I didn't know the background story on the Mandarin, I enjoyed the show. Great film and effects as usual, great plot, great cast, and outstanding lines. As for the focus of the film (Tony Stark) it ove deeper into who he is, his mistakes, his character, and rise to success. The film is a bit more violent than the preceding two and girls in bikini's are a must in this series, so wouldn't fully recommend taking small children to watch it. Overall, great movie.
