A lengthy and fractious political portrait of leftist radicals in Quebec, Those Who Make Revolution... is certainly interesting but it's not particularly good. Its formal tendencies, which run the gamut of Godardian voiceover to Godardian text on screen to theatrical asides, are mostly tiresome - the aspect ratio shifts aren't effective either, they're a superficial signalling of an "experimental" approach.
The directors situate their characters within a specific political history but then isolate them from that history physically. It's a detached hypothetical straining to be something visceral and affecting. It's an art film about political action instead of a work of political art.
