I went to see Iron Man 2 on 2 May (I know - a LOOONG time ago - hence the title of the post :-) )
Prior to the movie I watch the DVD of the first Iron Man. Really enjoyed the storyline and looved Robert Downey Jr in the role
The second one was good but not AS good. Scarlett Johansson was wonderful in her role (and in that skin tight leather outfit), and Mickey Rourke played a suitably bad villain, and I did like the special effects, but somehow it wasn't as exciting as the first one.
