Ever a fan of a good comic book based movie - Iron Man did not fail to provide awe-inspiring special effects. The scenes where Iron Man is putting on his suit never failed to amaze. The computer lab where Stark (Downey) worked to create and test his final suit was impressive.
While the special effects really made the story believable, it was the really great acting on Robert Downey Jr's part that made the film. He was the perfect flawed hero - arrogant and charismatic at the same time. Downey's transition from a cavalier playboy to a civic minded hero helped endear him to the audience. A great supporting cast also helped to develop his personality - from bantering playfully with his assistant Penny (Paltrow) to his sometimes thoughtless actions to his friend James (Howard) to his father-son relationship with Obadiah (Bridges) - Downey never failed to impressive with his wide range of emotions.
Even if you're not a fan of comic book movies - you will definitely want to check it out. Not only are the special effects top tier, but the acting brings the film to a new level. Not since Batman Begins have you seen a comic book film where the actor showed so much depth to his character. I would definitely recommend this to a friend.
