This documentary is good - 'OK' - but not nearly as in depth as the far better "The List Leonardo". The makers felt the need, apparently, to add a stupid crap snare drum effect and other melodramatic music. It's amateurish by comparison, and suggests that they didn't dig deeply; they were satisfied with a somewhat shallow narrative. See the other one for NUMEROUS jaw-dropping moments in a very professional & straightforward documentary, instead of this wannabe entertainment piece.
