I never buy movies on DVD. Once you have seen them you have seen them,no matter how good they are.
I do however own a copy of Baraka,which I watch on a regular basis......
No plot,no actors,no dialogue.
Simply sumptuous music and visuals from 24 countries around the planet,describing the beauty and stupidity of the human condition.
Deeply thought provoking.
