It's a Herzog doc so you can expect two things right off the bat: some stunning images and some inane contrivances. Herzog made a couple of documentaries where he didn't feature such contrivances, but this is not one of them. Essentially he sets up a conversation with the subject and asks about something he thinks affected their psychology then gets the reaction from them. This may be a standard documentary technique, but Herzog most certainly scripts many of these scenes in his movies, or possibly just tells the subject what to say. It's obvious and distracting and unnecessary, as the movie itself does nothing but discuss the exact same things discussed in that conversation here, but still Herzog feels compelled to include this scene to make things ultra-obvious for the audience. For a director so often seen as an art-house favorite he sure seems like he's pandering sometimes.
