On a similar theme I saw one of the most amazing, intense, harrowing movies I've ever seen in QFT at the weekend.
It's the story of the massacre of Palestinians in the Sabra and Shatila refugee camps in Lebanon when Lebanese 'christian' militia were allowed (and indirectly assisted) by the Israeli army to rape, pillage and slaughter around 3000 defenceless civilians over 3 days in September 1982.
Read about the massacre here- http://en.wikipedia.org/wiki/Sabra_and_Shatila_massacre
and the movie here- http://waltzwithbashir.com/
The maker of the film was a soldier in the Israeli army at the time of the massacre and the film shows his attempts to recover his memories of the incident. His own attempts seem to ask the question of whether Israel itself has made made a mass, semi-conscious decision to forget.
The movie is shot as an animated documentary except for some real footage at the end. When it finished nobody moved. Everyone just sat rooted to the spot staring at a black screen for what seemed like an age, reminding me of when I first watched 'Schindler's List'.
So many questions fly round your mind after. Issues of war, mankind's potential for evil, the brutal oppression of the palestinians, the repression of unwanted memories, our world view, the world's view of christians etc etc.
