Alumbrones

Its undiscriminating focus, accepting artists whose degree of talent varies widely, may not help it with audiences seeking a fine-art doc, but many viewers will appreciate that very quality, enjoying this modest effort's celebration of a bootstrappy creative community.

Short and sweet and limited.

As the movie drifts from generalities about technique to vibrant scenery — evocatively photographed by Esteban Malpica — to the occasional, much-needed anecdote, the vagueness of his enterprise becomes increasingly apparent.

Alumbrones's creators talk up their work's restorative value, but never go into great detail about the world beyond their canvases. Donnelly's vague, circuitous questioning is to blame.
