Every so often, a film comes along that, as if out of nowhere, leaves an unexpected impression and a need to find a moment to take in all that was witnessed fully; it’s a phenomenon that can come from any genre, any type of project, any filmmaker or subject, from battles in a galaxy far, far away to the intricate life story of a media tycoon. Sometimes, the smallest forms of art end up being the most effective, with “Sugarcane” a perfect example of how to draw in an audience to the film’s powerful message with moments as shocking as any entry into the world of horror.
