Iron Man still holds up. Robert Downey Jr. was amazing as Tony Stark/Iron Man in this movie. It is hard to believe that he was the not the first choice for the role. Maybe this is partially the result of seeing Downey play the part six times.
The special effects were good. I thought the Iron Man suit looked good. I liked the scenes with Tony building the armor and learning how to use it. I also liked all of the action scenes.
I liked the rest of the cast. I liked Gywenth Paltrow as Pepper Potts and Jon Favreau as Happy Hogan (it is a small part, Favreau was busy directing the movie). Terrence Howard was likable as James Rhodes aka Rhodey (in Howard’s only appearance in the series).
