Land Without Bread is above all a metaphysical statement, with all the strengths and limitations that implies. It's also an intricate unpacking of the documentary form rather than a simple adoption of it, and a mockery of touristic observation in general.
This savage satire has no time to take prisoners because it's too busy wallowing in misery. One of the darkest comedies ever filmed, it pitilessly sends up the authority of the documentarian... I can't think of another film that has managed to be at once so comically and tragically desolate.
