I watched the first 90 seconds of that. I admittedly didn't get to maniacal laughter. But I saw nothing in the first 90 seconds that was all that controversial or terrible. In fact, I saw some stuff in there I thought was kind of admirable. Maybe taken a step too far, but still...
...Also, I am hesitant to judge Cruise on his beliefs. I mean, if you went to Hollywood hoping to be an actor, and someone got you caught up in a power-of-positive-thinking kind of self-help program, and said "you can be anything you want to be if you put your mind to it" and then you bought in to it, and then became the richest man in Hollywood, how on earth could you NOT buy in to it at that point, and want to share it with people?
