Query: Excellent Hong Kong police drama.

The 90's has been far from the golden period of Hong KOng cinema, but there are still plenty of stand-out films from this period. This ranks as one of them. Recently, some directors have fallen into the trap of putting style over content, but Big Bullet manages to reverse this trend. The story follows a demoted cop who joins with the Emergency Unit to capture two dangerous criminals. This unit has the usual mixture of cops each with their own story. However, Benny Chan has managed to create an excellent chemistry between the five heroic leads. Up against them are two of Hong Kongs great villains, Anthony Wong and Yu Wing Gong. Naturally the sparks fly spectatularly. Highly entertaining viewing.
