I was shocked by how badly this film was put together. From the way it's edited, to the choice of music (and how it's laid into the film), to the cheesy introduction shots of the contributors, the jump cuts and sound cuts (you literally hear the cuts during Matt Damon's interview), down to the way it's written: not just cheesy commentary, hyperboles, random links trying to stitch scenes together and things which are obviously been written without even looking at the film (There's a hilarious moment where the commentary says "this man is... etc etc..etc... " over the shot of the sky. We only see the "man" in question after a few seconds. That's film-making 101).
The most impressive vistas are actually stock shots (I even recognised some from the Shutterstock Library).
It is disjointed and confused, cheesy, one-sided and simplistic, but I suppose the core message is probably what counts here (and how they were able to get people like Matt Damon and Liam Neeson), which is also why I'm not giving it 1 star.
There are some interesting snippets here and there and however badly the film is made, it does paint a promising picture of how new technologies are helping us to manage, clean and re-use our water.
It's a shame that such an important message was only able to get such a bad piece of film-making. Even more astonishing that it currently has 7.3 on imdb.
