"I think it's amazing," Clark told the panel. "I can't watch it the way most people do. For me, it's reliving a nightmare. It's a very painful experience.

"But that's a measure of how good [the show] is. They're getting the big stuff so right, they really nailed the racial issue in the biggest way possible," she said.

Kim Goldman, the sister of Ronald Goldman, who was killed with Simpson's ex-wife Nicole Brown, said she was in tears watching the program.
