Undeniably it is extraordinarily filmed, as clear as looking through a window, into a world we would otherwise have no access to; but structurally it is totally incoherent. It goes from one subject to another in a manner so distracted it seems to be made for those with no attention span. It's inability to focus means we come away having learned nothing. Imagine the power of this work if the effort that was made to get such amazing footage was actually developed into a cohesive narrative about the natural world, its beauty and splendor, and our impact upon it. As it is, it amounts to a collection of arcane facts. What an amazingly wasted opportunity.
