When I went to this movie, I could hardly wait for more awesome Iron Man action, but I left the movie wanting more, more, more! The storyline and the multiplots could have been left out and replaced with more action scenes. The dialogues and scenes between Pepper Potts and Tony Stark (read Tony's incessant babbling) serve to heighten the sexual tension the two have for each other, but have little other purpose (Why did he bring the strawberries?). The "disease" consuming Tony from the metal in his heart and the need for him to "discover a new element" to solve it was as unneeded as the confusing key to solving the riddle from his father's old movies. War Machine was severely downplayed only because it was after Iron Man for the majority of its screen time. It would have been nice for the two of them to have more than 60 seconds of working cooperatively to take out the bad guys. One other minor detail--the scene where Pepper tosses the Iron Man helmet out of the airplane and Tony jumps out after it is not in the movie. Otherwise, it was an Iron Man movie, all in all.
If you haven't seen this movie yet in IMAX 3D, you NEED to. The flying scenes make you feel like you are flying--much like the Soarin' Disney attraction. This film will make you question your morals and wonder what you would do if you were in a situation like Jake Sully. The basis of the movie parallels our society with the growing dilemma of our encroachment on nature and wildlife. The colors are vibrant and beautiful, and the animals, ships, and mechs are highly detailed and realistic. You will leave the theater wondering how almost 3 hours passed so quickly, and wanting more of this masterpiece. If you do not find yourself sucked into the world of Pandora, then you do not have an understanding of beauty.
