I like the Pegagogy of the Oppressed and the writings of the Socialist Filmmaker colelctives in Berlin who basically say - what others did say, too - that as journalist and film maker you are a soldier in the war, the war for socialism of the working class. This means you have to be partial partial to the working class and the structures of society, else you are only a negative propagandist furthering the talking points of the capitalists, who print their own news e.g. Springer.
