This documentary is not to bad, it could have been better. A&E goes and states in the documentary that Mussolini was wounded fighting in the Alps of Italy, wounded by a grenade that went off near him, and in another instance they go and say Mussolini was a coward and never seen any action (duh).
At the end of the documentary they have an interview with Mussolini's grand daughter, she is definitely worth watching. You also see fascism is still alive today in Italy. A&E also shows Mussolini in Ethiopia, footage of his death, some speeches, the blackshirts, and other things.
This documentary could have been more pro Mussolini but with a title like "Mussolini, Italy's Nightmare" what do you expect. In my personal opinion Mussolini was one of the best things that ever happened in Italy.
