Well, unusual for HK. A competently-made and very well-photographed thriller/horror film with almost no special effects, fairly low on blood'n'gore but nevertheless delivers a few shocks (if rather mild ones). Also, this is the only HK film I've seen with such lovely (or, for that matter, any !) underwater photography.
Reviewer Score: 6
Interesting for the intro of two well-known actors, Alex Fong and Elsie Chan. Alex displays a commanding presence, and must have shown potential even then. And Elsie took every opportunity to flash her excellent cleavage in a very flattering swimsuit.
But there's no nudity here, so the credit of "naked woman" at the bottom of the cast list is a puzzle. If there was a naked woman anywhere there, she must have been well-covered.
The subtitles were nice and large but, unfortunately, they mostly feel out of the bottom of the frame.
The story is unremarkable, following the conventional normal-life-gradually-gets-creepy formula, with several nods to JAWS. The ending is clearly telegraphed at least twenty minutes before, so the end is almost a groan, and a bit hard to swallow.
Overall, pretty good and undemanding.
