Short horror chiller Agatha is a masterclass in Gothic dread This review will be short because the film we’re discussing here, now, in this space, is short. Eight minutes from head to tail, to be exact. But nestled within those eight minutes are more unsettling and stylish passages of dread than most feature length chillers could ever hope to posses. The movie in question is Agatha, a shivery sliver of a picture, written, directed and edited by Timothy Vandenberg.
