“Blurry” isn’t triumphant, strictly speaking. Instead, it relies on the accretive power of the mundane. It moves forward without narration, and sometimes without narrative rhythm — often it feels almost observational, like a nature film.

It is a poem about the ways in which the speed and ubiquity demanded by the internet have squeezed certain creative wells dry, perhaps irreparably.

The director, Kate Novack, has delivered a film that’s detailed and affectionate, but also frustratingly static, making a point not to get in its subject’s way.

In a scene puzzlingly late in the film, Mr. Blahnik, who apparently still makes samples by hand, walks through his factory and finesses a sensuous heel out of a stump of wood. More of that would have made this confection about a radiant man into something sturdier.

Much of this film is told through interviews: Mr. Kani is fascinating and also funny; Mr. Combs is cocksure; and Kanye West is appealingly hyper. (“Being fresh is more important than having money!”) The film is rounded out with great archival footage and, especially in the first half of the film, excellent cartoons by Hectah Arias.

This nonjudgmental documentary moves between New York City and the rain forests of the Central African Republic, where Mr. Sarno primarily lives. Both places are tugs of war between abundance and lack.
