IronMan 2 was a missed opportunity. The spark, the magic that made the first movie so special, was all but lost here. The inclusion of Sam L Jackson as Nick Fury and Scarlett Johansson as Black Widow was completely unnecessary in terms of plot ... what one earth where they doing there? Talk about blatantly setting up the Avengers franchise. But on the strength of IronMan 2, I can't say I'm excited by the prospect. The big flaw for me was that Mickey Rourke as Whiplash was hardly in the movie, and as for how Don Cheadle becomes WarMachine ... sheesh! His motivation for grabbing an IronMan suit as Tony's party gets out of hand was totally unrealistic. As is often the case in franchise flicks, No.2 was bigger but by no means better. And, crazily, there seemed to be a severe lack of action until the very end of the movie.Number three has a lot to do ...
