"To enjoy this work one must view it as a film not a documentary. It's drama. It's fiction based on fact.It's a lie well-told. It certainly sustains the viewer's attention. It's hardly boring. Well-structured story, very well acted and cleverly written. Maybe not to everyone's taste but if you read the reviews, watch the trailer you'll have a good idea if you're likely to enjoy it. It's not the best film of the year but it is certainly very good and well worth a visit to the cinema."
