All Light, Everywhere (2021) review

This essay film from documentarian Anthony starts with the idea that the eye has a "blind spot" - and that the human brain has to "fill in the rest" - and proceeds to examine modern companies developing new visual technology like Axon International (who make body cameras for police officers) and Persistent Surveillance Systems (who record activity on the streets from the sky), while offering some commentary about chronophotography, the Janssen revolver and Alphonse Bertillon's work in the field of anthropometry.  It's a bit of an understatement to say the subject is way too broad and complex for a single movie (and brings up too many side questions that it never truly gets into) and much of the "philosophical commentary" (mostly via voice over) is largely trite - it only gets literally brought down to Earth when they record a community meeting in Baltimore where some citizens complain about being filmed without their "consent," and that's about as alive and hotly argued as it gets.  It's ambitious, but kind of naïve: when Anthony asks the one tech guy if "this is what God sees," that's a question I'd expect to hear from an elementary school student.
