About the movie, I thought Iron Man 2 was better than the first Iron Man. It was funnier, more action, Robert Downey Jr as Tony Stark was more arrogant. Sam Rockwell's character Justin Hammer should be mentioned here, great character. Please look out for his hand. It looks like he didn't wash his hands properly after applying fake tan.
I just don't understand the hype about Scarlett Johansson's role and her fighting scenes in Iron Man. Firstly, she hardly appeared in the movie and when she did, she didn't speak. Secondly, her fighting scene (it was only one!) was definitely performed by a stunt woman. But I guess she looked very ft and toned in that lycra suit.
I would definitely recommend to watch Iron Man 2 and it is not just a "boys movie".
