Without meaning to be derogatory this is a classy B cast. The great set designs and lack of lighting add to the depressive atmosphere of the screenplay. You get the feeling that this film will hang around for quite a while yet.
All the characters have a special gift even if some of the gifts are a bit on the corny side. The action segments gradually over power the sci–fi. ideas. There are some good shots of Hong Kong streets.
The production values are consistently high throughout. The performances are very good but the highlight is the suspenseful tunneling scenes. The ending is a bit melodramatic though.
