Robert Downey Jr.'s performance elevates a decent film to a great one in this adaptation of a classic Marvel comic.

During a period where film adaptations of Marvel comics were falling off the deep end, "Iron Man" came as such a pleasant surprise. The storyline is not unlike that of a certain caped crusader — billionaire industrialist Tony Stark is orphaned at a young age and takes up the superhero mantle later in life. Jon Favreau keeps the action and effects as streamlined as the film's pacing, all of which harmoniously pairs with a brisk, witty script to make this one of the rare examples of a popcorn flick done right.
