To its credit, this documentary deserves a lot of credit for tackling a subject that is rarely treated so extensively in nature docs. Moreover, the makers of this film should be creditted for making episodes that cover, ostensibly, unusual habitats that would scarcely get mentioned in most docs, like water tanks.But the biggest problem with this documentary series is the script. How would I describe it?-Largely fact-free (maybe one out of ten statements have a nugget of fact in them; the rest is fluff)-Distractingly hyperbolic-Heavy use of hackneyed phrases and cliches-Very non-specific about the subjects (locations and species are rarely identified)-Excessive anthropomorphism of animals, and even inanimate objects.So, if you are disposed to enjoy docs, you might like watching it despite the problems above. But odds are, you'll just be disappointed.
