This formidable film is sometimes zealous to a fault: The credits cite more than 200 sources of archival material, from The Washington Post to YouTube channels. It’s a lot to take in, as names and numbers zip by, yet missing some of its points may be healthy. To explore every moment is to risk overdosing on outrage.

“Is This the Documentary That Can Take Down Trump?” asks the headline of a recent article on the film in Vanity Fair. The answer: probably not. Much of what’s asserted here has already been reported elsewhere. Yet if, by the end, you’re angry about what you’ve seen — and you’re likely to be — Mr. Bryan will probably be pleased.
