I enjoyed the movie from beginning to end. It is a good movie for adults and kids. My friends and I specifcally wanted to see the movie in 3D on an IMAX screen. The IMAX experience enhances the 3D in my opinion. You do have to pay a little extra for IMAX, but this movie was worth the extra cost.
I am one of those "people" who grew up reading Iron Man. But I'm not a diehard fan. I do not expect the movie to reflect the comic in every exact detail. With that said, Marvel did an excellent job translating the story from the comic book to the movie screen. You can watch without knowing anything about Iron Man and you will not be lost. They took some libertys with characters but overall it enhanced the movie and kept things moving. The story was good. A nice mix of humor, action, and drama. I am glad Iron Man was the first summer blockbuster to be released. It set the bar high for the other movies coming out this summer. Go see it! I promise you will like it.
