It's a great movie that is worth your money. It has an 8.8 or something along those lines on imdb. I think it was much better then spider man and on par if not better then batman begins.
I haven't seen the movie just yet but I heard that the guy who plays as Tony Stark did the job perfectly. IRON MAN is my favorite super hero then SPAWN.
I don't have much hope for any Marvel comic movies. The last one that was even worth watching was Spider-Man. But, I have heard that it's actually a very good movie.
