This film is a lost opportunity for knowledge. It is more about "you are there" and didn't miss anything, now hat you've seen the film. We heard experts gush about their personal responses to the painting and drawings. There was no contextualizing where Leonardo fit into the history of art, and no idea of the frantic nature of his life between Milan and France. Teasing mention was made of cartoons under paintings which were xrayed but not shown, and restoration work removing dirty varnish not shown as well.
