I thought it was an exceptionally good movie, about as historically accurate as possible, and the ending reflected the most heroic of the available accounts of < SPOILER ALERT> Gordon's death. Actually considering current events maybe there will be a remake, "Kobane", without the heroism, only the bloodshed. About 10,000 residents of Khartoum where slaughtered, and they were never offered the opportunity to surrender.
It struck me as a generally well made movie that ran out of money before they finished the story.
