Despite occasional lapses in believability, particularly surrounding Cassie’s improbable involvement in a police investigation, the film benefits from the compelling mentorship between Cassie and Mikael, as depicted through poignant flashbacks. However, the premature revelation of the killer’s identity diminishes the suspense, although standout performances by Olwen Fouéré and Nick Dunning inject the narrative with much-needed complexity and gravitas. Set against the breathtaking backdrop of rural Ireland, “Cult Killer” offers a riveting exploration of trauma, intrigue, and moral ambiguity, blending familiar genre tropes with fresh twists to keep audiences enthralled throughout.
