I enjoyed the video immensely.
I have seen Dawkins in direct debate with creationists a few times, and I have to say I was impressed with Wendy, as an adversary, she probably put up better arguments than those I have seen before her, though I felt she was getting a little repetitive towards the end of the debate, she did not rely on scripture or words from the Bible, but argued more from an ethical stance, which I think added to her credibility.
She made some good points on how condescending Richard could be; enjoyable as it is to watch, it probably isn't conducive to good dialogue; she also gave me more insight in to the creationists views than I had previously held.
I also enjoyed watching Dawkins telling her about evolution; you could see his face light up, and could really see where his heart was. I believe he genuinely wanted her to appreciate it for herself, and for a moment, you would not have known he was in a debate.
It left me in no doubt that education is at the heart of his drive to end the muddying of the waters where evolution is concerned.
