The Tactical Unit series continues, and quite possibly is getting better, if not more explicit. If you are familiar with the other films or PTU proper, then you know exactly what to expect. If you are unfamiliar with the series, then this, like the others, follows the a group of police officers in the city of Hong Kong and a certain series of events in which they get involved.
This entry is essentially devoid of any action, but is well directed. The acting is solid, and audio is transparent, bordering on non-existent. The story is good, and it is very well written, even though it leaves little screen time for the officers themselves, it does focus on a couple who live in the underbelly of the city and their tragic lives.
This is very good, likely not one for multiple watches, and not the best entry point for the Tactical Unit series, but it is as good of an entry as one could or should expect in a good series.
