This film is essentially preaching to the choir. Which is fine, but not really entertaining. Nor does it seek intelligent debate. When you have a film that opens up with someone saying "Science is beautiful and right, and religion is not beautiful and not right" - you know what you are getting into here - people who are just as closed minded as those they are accusing of such.What I don't understand is why these people who pride themselves on being smarter than everyone else have nothing better to do than to try to convince believers of any religion that having faith is wrong by means of trying to make them feel stupid. If it makes people happy why are you interfering?What baffles me is how these so-called geniuses condemn "religion" so readily and yet can't accept the concept that a higher being is responsible for their scientific findings. Funny enough one of them even says "to assume the truth without asking the questions leads you nowhere" - yet he is assuming within his own beliefs - which is that natural selection etc occurred without the presence of a deity.Anyway, people these days don't want to hear anything contradictory to their own world-view so this film that attempts to be smart is actually very dumbed down, knowing that it is essentially just telling a certain group of people what they already want to hear.Because it refuses to understand the other side of the debate it is not brave, it is not exciting and it is not intelligent. But Ricky was in it so I'll give them a couple stars for that.

Deeply intelligent world-changers such as Krauss and Dawkins deserve a better documentary than this. If I were to rate their thoughts and views on the world and on science vs religion, I'd easily give this film a 10. But since I am rating the documentary and NOT their views I can only give The Unbelievers a weak 5 out of 10. The documentary doesn't share any new knowledge, any interesting new facts or any conversations beyond the most simple interviews, etc.Anyone on the hunt for deeper knowledge will be disappointed. I really have no idea what the film makers tried to tell the viewer? PS. All the celebrities featuring in the cast list are just a smoke screen. They don't share anything of value and are only on screen for 1-2 minutes combined. DS.

It's very funny to read "reviews" of religious zealots who --I'm pretty sure-- haven't even seen this movie. But the most hilarious part is them claiming that being an atheist is a "belief system." Yeah, as much as being bald is a hair style, as Bill Maher aptly said. And it's interesting that you will hear that very same argument (or lack thereof...) from the science-haters throughout the entire movie, as the base to criticize rationality is, obviously, sheer irrationality. And it's so rewarding and intellectually stimulating to watch two great scientific minds mercilessly destroy the childish make-believe world of religious people with arguments that can only be attacked from a very irrational and nonsensical perspective.Despite being an ardent admirer of these two gentlemen --not to mention a scientist myself-- I was hesitant to watch this movie, because I assumed it was going to be a tad on the boring side. We all know the argument and we all know what the irrational minds (and I'm generous about that last word...) keep saying in their endless battle against reason, so I wasn't really in the mood for another round. Surprisingly, this movie is more of a "behind the scene" look at these men and only occasionally shows a debate with the anti-science crowd, though I must say that the scene with the Archbishop of Sydney was hilarious.In other words, it's no so much about the reason vs. religion debate as much as it is about these two extraordinary men, their subtle sense of humor and a slice of their daily lives. All in all, a very enjoyable documentary which only the religious zealots can hate.

If this film tried to argue its position, i wouldn't have rated it so lowly. Unfortunately it doesn't, it is only a propaganda piece. It uses emotional arguments and the cult of celebrity in attempt to endorse a belief system. Meanwhile, one of the stars of the film in Richard Dawkins runs scared from open intellectual debate with Christian apologist William Lane Craig. This is a scientist who claims to be an advocate of reason who chooses, rather than debate his position in open forum, to instead use the cult of celebrity to convince the human cattle that his belief system is the one and only true belief system, and all others are wrong.If your intellectual capacity has run so dry that celebrity endorsement can convince you of any belief system (ie atheism), this film is for you. For those of a more critical nature, this film is offensive.
