This is a typical HK police action film, the one thing sets this one aside from the crowd is that the story is inspired by real life events taken from Japan. The villains in this movie are the cult members that did the Sarin Gas attacks in the Tokyo subway. Its an interesting " What If " film where they explore the possibility of terrorist attacks in HK. The story in itself is basic and easy to understand.

There are several characters in this film but the main focus is on the 2 police officers and the leader of the terrorists. There is little depth to the characters and this make most of them quite ordinary and unimportant. As for the main characters they were good as far as their roles but once again they lacked depth. The character we found the most interesting in this film was the leader of the terrorists, he seemed quite psychopathic or on some kind of drug, very good acting on his part.

There was a lot of good quality action in this movie. At least half of the movie was action, mostly gun fights and the occasional car chase or stunt. The special effects were of a good quality, the action scenes were nicely filmed. You have many explosions to keep you on your toes during the action scenes, there was also a nice scene with the SDU (special duties unit, HK swat team).

The subtitles were small but always readable. This is first and foremost an action film, and in that sense it passes with flying colors. It has a decent story to back it up but the cast is so so. For anyone looking for a good old fashioned action movie with lots of bullets flying and a big explosions, this movie will do just fine.
