I liked it. I thought it was indeed very thoughtful. But, you can tell he gets his observations from primarily a Protestant view of Judgment and hell and simply shows the weaknesses of that viewpoint. He doesn't realize that Judgment Day is about the revealing of what we really are to ourselves. This complete exposing of our true selves is a natural consequence of being exposed to an unspeakably holy God. Think Isaiah. Hell is not vengeance it's our reaction to being exposed to this God, His love.
The other problem is that he is using scientific, rational means of determining if there is a God or not. As Hebrews says one must believe that there is a God and that He is a rewarder of those who diligently seek Him. If you start out saying "God must prove Himself to exist using my standards" you're probably not going to get very far.
Anyway, I was impressed w/ this guy and appreciated his mature irenic presentation.
