What does it say about people presumed to know a great deal about the art of movies but who put down or dismiss a film that eschews conventional drama (intimate revelations, emotional moments, striking plot turns) but delivers like a wizard in terms of convincing the viewer that what’s on-screen isn’t a product of the usual prepared trickery but something intensely scrupulous and honest and, as far as it goes, as “real” as it gets’? What does it say about people who see a film like this and go “meh” ? You can’t watch a live-wire film like Che and say “give me more.” It is what it is, and it gives you plenty. Take no notice of anyone who says it doesn’t.
