The movie is, I think, good of the style. It is not boring, there are experiments shown and both sides (ie, the conspiracy theorists and officials) are felt in approximately equal number of times to speak.
However, I must say that in my opinion that initially tried objectivity of filmmaker ever more clearly in favor of the official declaration wanes especially from the second half of the film - so you should expect eventually, especially if you perhaps even more likely to be believed conspiracy theories.
I think the experiments well, but I find it very unfortunate that the conspiracy theorists were set just before the camera to the experiments, which are to refute the theories to watch. Since the officials were, may disprove the conspiracy theories, I find it very partisan, that the side of the conspiracy theorist has not received the same chance - has not given the opportunity to speak their own experiments to prove their own theories on camera. So they could only talk about his own experiments or their own knowledge and that of course is not entirely fair, if you really want to professionally and objectively approach the matter would - I hope I was of course: D
Finally, is succinctly addressed the existence of conspiracy theories, so why they occur at all and talk. The grounds that conspiracy due to psychological components arise / chat, I also think not objective and I had on this part of the film, since it is shown without any counterargument, also can well do without.
Still, all in all a "nice" film about a terrible issue, and like the people have lost the time someone or seen the horrors have to be strong.
