Can't say too much without giving crucial elements away. Just saw this at a screening in Boston and thought it was one of the more clever independent films I've seen in the past two years. Any cinema buffs, sci-fi fans, or documentary-lovers would find this a very inventive, well-executed, and highly entertaining piece. It seems like it would be unforgivable of any fan of Werner Herzog's to not see this film. You don't need to be a fan of his films to thoroughly enjoy this doc though. I have never seen one of his films before, but I went right out and rented two of them after seeing this film. Great cinematography, fantastic drama, some laughs, and some pretty terrifying footage that you won't believe you just saw!
