Visually appealing and riveting! This film by the Pang brothers gets the viewers' attention for the suspenseful story and well-edited shots.  Lead star Aaron Kwok as Tam seems a perfect fit for the role as detective and his portrayal is commendable.  The acting performance of the supporting is also laudable. This story of deceit and paranoia won awards at the Golden Horse Film Festival and the Hong Kong Critics Society Awards. Interesting to note that main star Kwok, aside from being an actor is also a famous singer and dancer in Hong Kong. Highly recommended and if you're into suspense flicks this will surely be to your liking.
