I Am feels like a terrible song written to raise money for a natural disaster: While the song itself may be terrible, you admire what the band is trying to do to help the cause. I admire Tom Shadyac for having the courage to sell his mansion along with his status of being one of the Hollywood elite in order to become a better human being, but it probably deserved to be a story on Oprah, rather than the focus of a documentary.
This entire documentary can be summed up from one piece of dialogue taken from the film:
While Shadyac is having his mind read by an electrolyte filled clump of yogurt (don't ask), he turns over to the scientist who designed this bizarre experiment and asks "Do you know why this is happening"? The scientist then shrugs and replies "Not exactly."
Well put Mr. Scientist, well put.
