What I found interesting about this programme in comparison to the others was the candidates themselves:
One was extremely academically bright, so could come up with new ideas to build on an already strong foundation.
One didn't appreciate at the start the need for perfection and had to learn this appreciation.
One was exceptionally bright and had bipolar disorder, which meant that through their life experience and as a side effect of the condition they were not restricted by subconscious conventional boundaries that the other two would be subject to.
It was fascinating to see not only the ideas they came up with, but also to read up on how they've developed since the programme.
