“Only Mine” (**1/2 out of four) was a mildly diverting thriller melodrama about a young woman (Amber Midthunder) who is captivated by a charming cop (Brett Zimmerman) and they begin a relationship but once she tries to break it off, she realizes he is a serious sicko who doesn’t take rejection or heartache easily. Yet another “Fatal Attraction” clone with predictable plot twists and the usual logic gaps but it’s better than average, due to a solid cast and interesting dramatics involving the police and its subsequent internal affairs investigation.
