The story goes that Jing Wong went to Canada to convince Donnie Yen personally (and got what he wanted). Wong will never be the greatest director alive, but it's little anecdotes like these that show he has a heart for cinema. Together with Jason Kwan, Wong delivers a pretty fine crime flick.
This retro drug setup was made with a healthy budget and it shows. The cinematography is slick, the action scenes look pretty good and there's no lack of talent in front of the camera either. With actors like Andy Lau (he simply doesn't age) and Donnie Yen fronting this film, you can rest assured that there's no lack of charm.
It's also nice to see Kowloon again, even if it's just a CG version of the infamous "city". It's such an amazing place that wasn't used nearly enough in its time. The only thing this film lacks is real highlights, apart from that it's an entertaining and slick production that does justice to its genre roots.
