I like comic books, one of which was Iron Man. So for that reason I could appreciate the story line in the beginning, because although the beginning was slow it payed homage to the original comics. Also Tony Stark (Robert Downey Jr.) is an extremely entertaining character, with many funny scenes. Another great thing about this movie was the graphics, the way they brought Iron Man to life was epic!
The movie is very similar to that of the comics only Tony Stark was inured in a different war (although some people say its pretty much the same war just with more sand, but thats an entirely different topic). Anyways Tony Stark is indurged from shrapnel from a road side bomb, and he has things magnet thing in his chest that he needs powered up to survive. Stark builds this bad ass suit to escape from terrorists, and latter goes home to build an even more bad ass suit.
But what bothered me about this movie was the ending, its almost as if the whole purpose of this movie was to make bank on another Iron Man movie (which they will, and I will probable enjoy much more). Now their is a lot of people saying this movie is absolutely fantastic, but don't get your hopes up, because although it is entertaining it is still not as good as Transformers, Spiderman or Batman despite coming pretty close.
