Keeper is the kind of film whose value grows with consideration. The movie’s strength lies in its powerful atmosphere and striking visuals, demonstrating Osgood Perkins' skill at creating immersive horror settings. Tatiana Maslany delivers an outstanding performance, complemented by truly remarkable visual effects and makeup artistry. It blends psychological and folkloric horror elements to transform damaging relationships into a visceral experience, prompting contemplation about power dynamics even after the credits roll. It’s a disturbing exploration of compulsion, serving as a reminder that genuine fear can be found in the compromises we make and the monsters we harbor." Rating: B
