Written in part by a journalist who has dedicated much of his career to this true story, it unsurprisingly doesn't deviate from the perspective that the conspiracy the movie presents is true.
It may well be the case that the version of events on offer here is the truth, unfortunately, that doesn't guarantee a well-told story. The quality is a little rough around the edges. For a movie so focused on a real-life story, it's really lacking in telling that story. Everything just tends to drift by from scene to scene with very little fleshed out. It gives the impression that the makers were overly cautious, and as such used as little creative license as possible. This movie presents its story at the expense of entertaining you. The main cast do put in a good shift and work well with what they're given. Don't be fooled by the cover as Angelina Jolie isn't in the movie for long, but she does steal the show when she appears.
The ending might well be as far as the story goes at the time of filming, but it won't leave any satisfaction.
