Richly developed characters.

So I was reading the calendar section in sundays paper and came across the article about "Saving Grace" staring Holly Hunter. And i was surprise to hear that the show had been cancelled. She explained that she did not want the character grace to be born again or have her lose her essence. It seems to me that grace was having these wonderful experiences but was unaffected by them. I mean some people really don't change even by life threatening experiences. Or they change for a minute then change back to who they really are. I get that. Thats real. Thats grace. Although i liked grace, I did not understand her. I kept asking myself, why does she continue to behave this way, what's going on with her. There was no real connection. I wanted to see a different side of grace not a changed side, just more of what makes her tick. Instead of this is who I am, Take it or leave it. I guess folks decided to leave it.
