Iron Man is fun, good entertainment that targets a teen movie audience. Iron Man is worth watching for the excellent special effects. Don't expect great plot or character development - it is based on a Marvel comic book after all. This is not Academy Award material worthy of 5 stars. The story is slow to get off the ground, is fairly predictable and has inexplicable comic book plot devices (e.g., What is Tony Stark's technological savior after his capture by terrorists doing in a small village in Afghanistan? Why doesn't Tony just have the shrapnel removed from his chest after his rescue?) You also have to suspend disbelief about the technology that Tony uses (e.g., Tony's robotic AI assistants and totally automated assembly of the Iron Man suit in 5 hours while Tony runs out to a party.) The acting was good, but the characters and their relationships were stereotypical Marvel fare. The script even makes a self-depricating reference to the formulaic tension in the semi-romance between the hero and his assistant. The movie's most interesting and humanized character was Tony's assistant, Pepper. Iron Man was clearly written with a sequel in mind - the seondary villian survived to fight another day. It's a sequel that I'd definitely see.
