Don't listen to the negative reviews

Fun premise, good actors, bad writing. This film seemed to have potential at the beginning but it quickly devolves into a trite action film. Ultimately it's very boring.

A great movie, one of the best of this year. There was a bit of confusion at one point in the plot, but nothing serious.

All of these films share one commonality, that being a kind of emotional center that humanizes a cast of monsters.

This movie pretends to be a science documentary but is pseudo-science driven mockery of real nature documentaries like Nature and Planet Earth. It is fun of the logical fallacy of the "Golden Age" of people. How the modern world is Evil and ancient people knew all of the ways to live and all the medicine. The hosts of this documentary all have lots of initials behind their names that all proclaim them to be Non-science based. Their goal seems to be that we should revert to a completely primitive aboriginal society without realizing the incredible down sides. Don't fall for their pseudo-science mixed with beautiful images and mindless platitudes.
