So I just got back from one of those 8 p.m. advanced screenings of Iron Man at my local AMC theater. I am being honest when I say that this movie makes up for all those awful superhero movies that have been made in the past including Dare Devil and The Hulk. Robert Downey Jr. does a great job in the role of playboy Tony Stark, a man with the philosophy that the best weapon is one that only needs to be used once. To my knowledge from hearing from others, the movie stays with the comic book with a updated time frame.
Another thing that looked amazing was the CGI. From the fight scenes to the suit being assembled, it all looked pretty good. I easily recommend the movie to anyone, just make sure you stay till after the credits for the second of the two noticeable references to the future of the comic.
Something I did not care for was the last line before the credits because from what I took after looking online, it was something that got changed and anyone who knows the comic series will probably know what I mean.
