My husband is a dyed in the wool comic book/sci-fi nerd, so I am dragged to any and all movies that have anything to do with this type of thing. Robert Downey Jr. was a wonderful surprise- passionate and driven and the effects were fantastic. I was really mesmerized by the technology that Starks was using as he built the second iron man suit. Even Gwyneth Paltrow was believable as Pepper Potts ( and I am NOT a fan of hers). I plan on seeing it again with my son (age11) later this summer.
