I have recently watched two political documentaries. First, The Unknown Known. Second, Watermark.
The first one is about glorifying a psychopath. It tells of his exploits as he uses humanity as subjects of his experiments. Its only saving grace is its honesty as it is unquestionably political.
The second one is this one, Watermark, and it has absolutely none of this honesty. It is a documentary that uses the awesomeness of nature to disguise political propaganda. It is essentially babies and puppies. Cheap manipulation to sneak in an ideology.
A number of these "nature" documentaries is being made nowadays. Big, big, big money is being given to "friendly" folks in the movie industry. Pockets full of cash, they are taking their skills around the world (literally) and making visually high-quality films. Unfortunately, the price of this funding is a script that makes adults cringe.
Consequently, this kind of "nature" documentaries is meant to be played in mute. Mozart, Armstrong, (or Pink Floyd if that's your preference) are far superior material to listen to while enjoying the unspeakable magnificence of our planet.
Watermark is also boring at times. The political obsession coupled with a jejune understanding of society and culture compromises the choice of visual subject. If they cannot use as a weapon to hurl at you, they won't show it.
