The imprisoned heroine and the detective have two lines. The past overlaps with reality to frame and reason, which aggravates the tension and suspense of the film to a certain extent. However, because of editing problems, it sometimes looks a bit messy. Don't overly publicize the troubles of the police detective's personal family and life, let the film go down the line of the investigation, let the characters' personalities become full during the investigation process, and make the film look very clean. The imprisoned life of the heroine is heart-wrenching, but the reason for being imprisoned and the process of being rescued are too simple, and the degree of reversal and twists is not enough, but it does not affect the overall quality of the film. One more word: The heroine was so beautiful when she was young, like an elf, much like the young version of the Snow Queen - but the Snow Queen is not a kind elf (I don't know if this is a spoiler.)
