I just watched this twice in one day, so I have a very fresh recollection of it's contents. This is a very uplifting film, and is NOT supposed to be a scientific flick. If you want one of those, go and rent The Living Matrix, or read some of Greg Braden's books.
I AM is the story of a personal transformation of someone, who at the peak of his life, thought he had everything he could possibly want; Success, Wealth, Fame, Admiration, and yet, at the end of the day, that wasn't enough to make him happy. Through a series of interviews with viewpoints of different prominent (and some not as prominent) people from across the globe, he touches on the different cultures he encounters and how it made him aware that there is so much more to the life he's living. Only a small section of the film really involves him, as he shows the audience how the journey in the making of this movie is what prompted him to make changes to his life. As a result of these changes, he's a happier man, and being much more of service to others. Granted, it's hard to feel sorry for someone who is that famous and wealthy already, but he gives you a glimpse into his heart as he moves into his mansion, then closes the door at the end of the day and feels lonely.
This movie was truly professionally filmed (how could it not be, in the hands of such an experienced movie maker). He shows joyous wonderful moments, like when the Dalai Lama rushes over to hug a young girl with such enthusiasm that is becomes a truly heart warming moment. Another scene of a little boy laughing at the camera, in sharp contrast with a little boy in africa with sadness on his face. Let's face it, life for the majority of people is a struggle. For someone who has been given the best success that can be gotten, he's a good person for making this movie. I didn't find it self serving, as other reviewers have mentioned. He had no need to make this movie, but he did it for the greater good, and I applaud him for it.
