If your ratings are high and there's money being made, you're allowed to be a perfectionist in television.
I start with actors that I know personally or I know their work, and there are things about their work or their presence or their own personality that make a character, that exaggerates some qualities and suppresses other qualities. It's always a real collaboration for me.
I can analyse the trajectory of my popularity and find out why the peak was a peak and the valley was a valley - grapple with it that way - but I prefer not to analyse it that much.
