_Significant Other_is a very unique thriller that has a lot more depth than it initially presents. Performances are pretty good around the board and the story takes twists that keep the viewer on their toes. I enjoyed it and has been one of the better Paramount+ exclusive films. Sometimes the movie tries to hit you over the head at the themes it is attempting to present and that dragged the experience down for me a…

Human psychology is a hell of a drug. This is delightful. It is suspensful, well-acted, engaging and well-directed. The effects are as good as they need to be for this sort of drama, but most things center on great character-work, not effects of music-stings for jump-scares. I appreciate the craftsmanship that went into writing and directing this movie, and I wholly recommend it.
