The film's abrupt ending leaves many crucial questions unanswered, but that weakness doesn't detract from its overall power.

The filmmakers get astonishing access, eventually earning enough trust that they get to visit Guzman's family home and interview his mother, who proudly recalls how fascinated he was with stacks of play money as a child.

Driven by mostly Spanish-language folk music, the movie provides a potent if piecemeal counterbalance to the sensationalism of “Breaking Bad.”

For filmmakers Angus Macqueen and Guillermo Galdos, they've undoubtedly chosen a great subject for a compelling documentary. Unfortunately, they squander the opportunity with Drug Lord: The Legend of Shorty, and it's due to the common problem of contemporary documentaries, where the directors get so far in the way of their own story, that any context or objectivity is lost.

Save for the vague aura of danger surrounding Guzmán—which palpably engulfs the filmmakers as they get deeper into the cartel’s “Golden Triangle”—Drug Lord has trouble forming a coherent point of view.
