I have pretty much written Clarke off in this because he was a consultant on the film. Other consultants were not portrayed in the film and therefore are more reliable.
I also realize that as a character, he was needed for continuity. I just think the characterization is soft as a thank you for his help.
It's docudrama after all.
(BTW, I'm not watching live...I'm on the West Coast. I enjoy reading the responses and then watching for specific things when it airs here. Fascinating!)
And Cynthia McFadden at "Nightline" needs to learn the difference betweeen dramatized and fictionalized. She's such a twit.
