Drug dealers, serial killers, Satan worshippers and immortal Nazis are some of the ingredients of the bloody stew that is Ratline, a tough, well-made shocker from St. Louis-based regional filmmaker Eric Stanze. Ratline is not a “boo!” sort of horror flick. It’s not about stalkers in dark corners or monsters under the bed. It’s about the evil that men often do, if not necessarily in real life, then certainly within really nasty horror flicks like Ratline. It;s an angry, humorless film filled with sex and gore, but writer/director Stanze is not one of these independent filmmakers who;s simply in love with his own nihilism. He’s working from his own smart script that attempts to say something important about the murderous energies at loose in society. Ratline is not without flaws, but it’s an aggressively low budget piece of horror weirdness that defies expectations and is remarkably accomplished.
