Thought provoking and philosophical. You have to watch it with an open mind. Disappointed that John didn't stick to his point and he had to give up to the rhetoric, because his audience were on the verge of breaking down. Religion is the soft corner where people couldn't hear what other's had to say from a different angle, without calling it a heresy or sacrilege, instead of exploring the idea. The idea of religion is as worth pondering over as the idea of Black hole, space or universe.
Do watch it for the joy of knowing the unknown, questioning the unanswered. We have to question ourselves over our beliefs, that doesn't make us sinners but will make us more more knowledgeable about the beliefs and the facets attached to it.
