With the many documentaries that are coming out lately you are used to a high quality. Being because they are funny or because they are very interesting. Unfortunately this ticks neither of those boxes correctly. It seems to wander around like water would once you spill it ... no clear direction.
I think there is a very good movie hidden somewhere, but it will be tough for you to find it. It's a shame, because quite a lot of people would interested in more specifics rather just some "nature videos" and a couple of hints here and there, what goes wrong. Just when you think it is heading the right direction, it swerves and goes "wrong" again ... Shame
