The biggest plus is that the subject is terrifically interesting. As for minuses, there are a few. First, I don't care for foreign languages and the voiceovers going on at the same time - just don't like it. Second, the narrative jumps around going forward in time then jumping back a few years. Why not do it chronologically? Lastly, there were some inaccuracies, which are, IMO, unforgivable. If you are going to do a biographical documentary, read the person's biography first. That would seem to be a given, but it seemed not to be in this case.
