The film did a really good job of showing that Alex is, in fact, no adrenaline junkie. He was raised in an environment that pedestalized performance. "Good enough isn't." like his mother used to say. Seeking perfection is the goal. Not heightened emotion. If he were an adrenaline junkie he would have gone the route of Dan Osman and started rope jumping--or Dean Potter and started suite flying. I felt it was a story of someone so steeped in the idea of performance that he couldn't see the people around him.
