The first "Iron Man" was a good movie. Iron Man 2 is not as good.
While this new edition has a fine director, Jon Favreau and a wonderful cast, it has enough plots for three feature films; this is the classic case of less would have been more than enough.
In trying so hard to fill every moment with drama, the film fails to foucus in on any clear theme, Samuel L. Jackson is in the movie just to introduce the storyline for the next edition of Iron Man.
I get the impression that special effects was suppose to carry the film and so, writing a strong, clear story was not a priority for the producers. This film lacks the heart which made'the original work.
