This one was a geniune debate, but in an odd format. Instead of opening statements, the moderator asked the interlocutors a series of questions, starting from very basic assumptions about reality. Questions such as "Does our reality need to be scientifically verifiable or falsifiable?" and "How does one's belief or non-belief in God alter one's perception of reality?" and "What is the reality of free will?" and "Is there any ultimate purpose to life?"
With such questions as these, you may well imagine that the debate might be somewhat weak tea, and you'd be correct. While things do pick up a bit later on, I'd say that this on is not exactly worth an hour of your time, expecially given the annoyingly scratchy audio.
Here is a more uplifting review.
