Huge disappointment.The documentary came miles short of my expectations. The film creators have missed a one in lifetime opportunity.There is very little depth, the narration is very superficial. At least 60-70% of the film is wasted on boring and mostly hollow conversations and interviews with some irrelevant "celebrities", who have nothing much to say. Worse, the interviews take place in a lobby, and Leonardo's art is not even shown on the screen! The documentary is marketed as HD, but do not expect too many pixels. I would speculate that the material was shot with a regular TV camera.
