Some first reactions:
Variety: By returning to his roots, professional gadfly Michael Moore turns in one of his best films with Capitalism: A Love Story.
The Hollywood Reporter: His talent is evident in creating two hours of engrossing cinema by contrasting a fast-moving montage of '50s archive images extolling free enterprise with the economic disaster of the present. Given the desperate state of the world economy, this provocative film should find attentive audiences along with many angry detractors who will give it free publicity.
Time: Capitalism: A Love Story does not quite measure up to Moore's Sicko in its cumulative power, and it is unlikely to equal Fahrenheit 9/11 in political impact. In many ways, though, this is Moore's magnum opus: the grandest statement of his career-long belief that big business is screwing the hard-working little guy while government connives in the atrocity.
The Guardian UK: If Michael Moore's latest documentary lacks the clean punch of his best-known work, it can only be because the crime scene is so vast.
The Independent: This is all familiar stuff. Moore delivers his arguments in his usual scattergun fashion, mixing archive footage, interviews, sarcastic voice-overs and his own interventions. (He spends a lot of time on Wall Street trying to make citizen's arrests of bankers.) When you unpick the rousing rhetoric you quickly realise that contradictions and syllogisms abound. Coherence isn't his strong point. Even so, this is moving and entertaining fare.
