I loved Iron Man because the movie emphasized loyalty, restitution and the responsible use of power by individuals and nations. I also loved that unlike Spiderman and other Marvel supers, Stark isn't accidentally endowed with new skills. Albeit he is a tech genius, but his heroic journey mostly involves an arrogant man coming to grips with his own depravity and choosing to change. I found this to be very deep and engaging. I was however, dismayed to see quite a lot of parents with small children in the theater that were obviously well under 13. The movie is PG-13 for various violent sequences so KEEP YOUR LITTLE ONES HOME!!!
