Theater of Thought could've easily become a straightforward documentary about the evolution of thought and the fascinating science behind our brains, yet in the hands of Herzog, this topic becomes far more entertaining, as he approaches the topic with a wide-eyed wonder that lets this subject go down smooth.

One of his most piercing inquiries yet. ... Herzog is the clear-eyed student — at times amazed and delighted, and, at others, skeptical and alarmed. Amid the cryostats and nanoparticles and fiber optics, the clunky gadgets and impenetrable-to-the-layperson diagrams, he summons a wry and lyrical mix of awe and foreboding.

A characteristically playful documentary.
