Not only was the plot boring, but there was no real excitement or real sense of danger other than as advertized - an animation of a comic book character. The up and down personality traits of the Robert Downey Jr. character was difficult to understand why he was so obnoxious and then caring. I wanted to leave in the middle, but unfortunately for me, I have to see anything I start through to the dismal end. And, what was the kiss at the end of the movie with Gwenith Paltrow about? The best part, however, was played by Scarlett Johansson.
