Here is my review:
OK, the thing with making a journalistic book into a movie is that usually you need to construct some kind of narrative around it that was never in the original story. Plus, it doesn’t really work well in film to have 50 different character appearances to impart information to the journalist. All these stories that go into the larger picture in the book form need to be collapsed so that you have one actor representing things said or done or referred to by several different actual people.
But the added narrative, even if it’s invented, should have some kind of vague thematic connection with the original work. In this movie, it doesn’t. I would think that even people unfamiliar with Ronson’s book would find the whole journalist’s-wife-leaving-him-for-his-editor-so-he-tries-to-prove-himself-by-going-to-a-war-zone thing contrived.
Same goes for the ending as well, which just seemed like a last minute dog-ate-my-homework addition in order to inject some conflict and tension into the storyline, such as it existed. But really, these kinds of books which are largely just exposes, huge extensions of a feature story for a magazine, don’t translate into film very well. So maybe this was just a bad idea and doomed from the start.
