The movie comes from a book of the same name and was directed by someone from Scotland. Described as a psychological thriller, it's the kind of film some viewers might find unsettling. The suspense builds around something that happened in the past, which isn’t revealed until roughly the last third of the runtime, keeping you guessing throughout. We see flashbacks detailing the story of a mother struggling to raise her son, Kevin. The movie initially shows how happy she was before becoming pregnant; after that point, everything changed permanently. She felt unable to connect with her child and had difficulties from infancy onward. As he grew into a teenager, it became even harder for her to manage him and the situations he found himself in. Then came a shocking event that impacted the entire neighborhood and turned her life upside down. The film was shot in just one month. Tilda Swinton delivers what might be considered among her finest performances—perhaps even her absolute best. She deserved an Oscar nomination, and it's hard to believe she didn’t get one; that feels like a major oversight. The supporting cast also stood out, including John C. Reilly in a smaller role, as well as the actors who played Kevin at different ages. The overall tone was excellent, and the atmosphere perfectly suited the story being told. I regret not seeing this sooner—sometimes your taste in movies and your mood can make you miss something good by a narrow margin. It had been on my list, and I’m glad to have finally watched it. It's a decent film, but nothing particularly extraordinary about it. The theme is powerful, and it feels ripped from reality, especially given how common these kinds of stories are in the United States. If you're American or familiar with American culture, you might find this especially compelling. It’s not an uplifting movie; instead, it presents a factual look at parenting failures. The ending is disturbing, but there aren’t any surprising revelations in the storytelling. It offers a unique perspective, although I was let down by the tendency to blame parents, particularly the mother—it's quite depressing. That’s why the story begins during her pregnancy and continues until the final twist. Really, it’s the editing that creates the sense of surprise; otherwise, it's a pretty straightforward narrative. It's worth watching once. It is slow-paced and runs long, but if you think you can handle that, give it a try. _6/10_
