Definitely my favourite Iron Man film, and, truth be told, I liked it better than The Avengers.
The action scenes were incredible, the acting (Downey Jr and Ben Kingsley at their best) and story were top notch and the comedy was gold. People have complained about the twist with the Mandarin, but I feel that it was a fantastic change-up and divergence from the comics. It gave the movie more of a realistic and perhaps, more relatable story progression to the general audience – most of which would not be familiar with the Iron Man comics.
Very deserving of a 5 star rating. If you haven't seen this movie… it's time to move out from under your homely rock and watch it, because it's one of the best movies of the year, without a shadow of a doubt.
