Propaganda
In my opinion, what went wrong with this film was that the director had a point he was trying to make about the British Empire and to do so he twisted history and portrayed such a characterization of the Victorian age as to make this film propaganda. It feels like a movie made by a bitter man who was allowed to make the film because it was politically correct.
I am not an imperialist. I believe very strongly in the right of self-determination. Having said that, I would like to say that of all the empires in history, the British were the most humane and least brutal, and in the end, they gave most of their empire back to the native peoples simply because they were asked.
I am not British. I do not think that the British did the right thing in building an empire and I believe that much of what they did was morally wrong. However, as a student of history, I have to look at the Victorians and Edwardians without emotion and compare them in a rational manner to other powerful peoples.
Compare the Brits to the Mongols, the Ottoman Turks, the Romans, the Japanese Empire in this past century, the Russians, the Assyrians...I could go on. Compared to the brutality of, say, the Ottomans who would denude a region of people when they rebelled (and not take any pains to see that they were even killing rebels), the Brits were gentle. This reminds me of a Muslim Pakastani work aquaintance of mine who said once about the British "Those SOB's...how many people did they kill conquering India?" I didn't say what came into my head "way fewer than the Muslims did when they conquered India, because they did it by the sword and the Brits did it mostly with a pen."
You would never know from watching this propaganda piece that Gladstone, the Prime Minister at the time of the Mahdist uprising objected strongly to sending troops to Sudan because the Mahdists were "a people rightly fighting for their freedom."
I don't remember. Does the film say that the reason they launched the expedition was not to conquer anything or to stop the uprising, but simply to rescue Gordon, the British general who was trapped in Khartoum? I would be suprised if it did, because it might have made the British look somewhat sympathetic.
