A Cure for Wellness
An ambitious young executive is sent to retrieve his company's CEO from an idyllic but mysterious "wellness center" at a remote location in the Swiss Alps but soon suspects that the spa's miraculous treatments are not what they seem.
The wellness center is designed to evoke sustained horror (body horror, disturbing imagery, psychological dread) that defines the experience, with thriller/conspiracy elements present but secondary; thus horror is central but not solely a single genre.
Best for viewers looking for a scary, atmosphere-heavy, psychological, slow-burning and low-gore horror movie.
