one of ***those*** films -
Roger Ebert described such endeavors as films where the quest of the hero is scarcely more mad than the quest of the filmmaker - specifically in terms of Werner Herzog's blurring-the-line docu-fiction epics. William Friedkin has created here something of a miracle in cinema - a film barely above the line of being a documentary about its own creation. Others like this: Aguirre, Fitzcarraldo, Apocalypse Now, et al.
