Metacritic reviews

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.

“Theater of Thought” is a movie about exploring the mind – and if the mind we’re exploring most of the time is Herzog’s, well, there are far worse tour guides through this territory.

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.

A characteristically playful documentary.

Herzog’s latest is one of his weakest. Part of the problem, shockingly, is in the filmmaking; there are basic, unfortunate amateur missteps throughout.
