What really takes me out of the story whenever it happens are a few not so good manipulated photos and two occasions when a characters draws a gun, which felt both unexpected and not really necessary becomes it suddenly feels like a cheap action movie. But that's my only complains. The rest is a very convincing and entertaining conspiracy-thriller with sci-fi elements. The acting is good, especially from the "experts" and I'm very impressed by the work Matthew Avant and his team has done with finding locations - from the secret underground base to the impressive headquarters of The Church of Lunology.
One of the highlights is actor Dave Potter, playing David James, a "moon-escapee" who wants to tell his story. His performance is excellent, worthy of very price in the book, and reminded me a lot of the equally brilliant performance by Raymond J. Barry in Interview with the Assassin, one of the best mockumentaries ever made. The director, Neil Burger, went on to bigger projects like The Illusionist and Limitless, but his first movie is still the best he made.
