I delight in watching the whole process.
It begins with weird and wonderful egos and the initial inability to work in a team. Disgusting caterpillars.
Slowly, for the more diligent competitors, repulsive behaviour and ego is moulded into decency and teamwork.
As the process continues, you begin to learn about the individuals, and want the good ones to prevail.
Finally, a winner emerges and they have over the course of 3 months (our watching time, not sure if it's filmed over 3 months) emerged into a beautiful butterfly, their life forever transformed.
