While "Companion" doesn’t necessarily break new ground within its established style, Drew Hancock’s distinctive approach to a well-worn idea, combined with skillful filmmaking, creates an absorbing experience—particularly if you can steer clear of the trailers that give away too much. The combination of different moods, a disturbing feeling throughout, and thoughtful examination of difficult subjects such as trauma, affection, and dominance push this horror film past simple frights, creating a significant emotional and storytelling resonance that stays with you after it’s over. It's anchored by a remarkable performance from Sophie Thatcher, making this psychological thriller—which incorporates humor, romance, and science fiction elements—a notable early highlight of the year. I strongly suggest seeing it on the big screen, going in knowing as little as possible. Rating: B
