While the arrival of two very different horror movies under the same title can cause some confusion, this year’s Shudder/IFC film has a unique premise that sets it apart from almost every other horror movie ever made – a haunted house chiller told from the viewpoint of a dog. This has resulted in the film grabbing a lot of attention in recent weeks – not least for landing a 92% Rotten Tomatoes score – scoring a huge box office win, and instigating a 2000% increase in Google searches for a morbid question: Does the dog die in Good Boy?
