One of the best from Hong Kong
19 April 2006 | by (Australia) – See all my reviews

This movie should be compared to movie like Heat, even when the storyline are not the same. Movies like Hardboiled and A Better Tomorrow are predominately action-based, whereas this movie is more dramatic and emotionally-driven.

The main attraction is the mole hunts but it would not be as brilliantly done if not for the fireworks between the major characters.

The title from the explanation in the intro means "Endless Purgatory Road". This philosophy, to me, really made this movie more thoughtful. The two central characters both had to walk their road, in life and in their minds for a long time. Both had no choice but to keep walking. As they cross path, they were forced to play the game of cat and mouse by their superiors. While it is not certain who's the cat and who's the mouse, one thing is certain - the loser will die.

While there are four main characters, they are all males. This should be bad for any movie but I think this is one of the exception to the rule. The emotions and tension between the four were well-scripted and brilliantly played. It is no surprised each had at least one best actor awards in the Hong Kong industry. The sequels(2 prequels) will delve deeper into it.

Plotwise - it is hard to see any holes.

Seen it around six times, a lot for a drama.

I think you should ask yourself after the movie, "what would I do if I am in the same situation?". Right and wrong is harder to separate.
