It isn't as good as the original but Iron Man 2 is still a really good sequel. Robert Downey Jr. once again gives an incredible performance and is extremely charismatic. Gwyneth Paltrow, Don Cheadle, Scarlett Johansson, Samuel L. Jackson and Sam Rockwell all give great performances. Jon Favreau's direction is really good and it's consistently funny. The CG is impressive and the music by John Denney is good. However, Mickey Rourke is wasted as a forgettable villain and the final battle is a little short.
