Nick Britton’s review published on Letterboxd:
This is an excellent primer on Herzog's masterful ability to lose focus on the subject of his own documentary and his knack for finding the most awkward people to interview. I don't suppose you're necessarily here to learn anything other than the unorthodox ways Herzog approaches a topic--in this case, asteroids and meteorites. Even if this doesn't do much for you, stay for the brutal shade Herzog throws at the town of Chicxulub, dogs, and film school studies. And then stay a little longer for his take on Deep Impact.
