What makes it so watchable, even despite the stomach-churning violence, is Williams’s clever, non-chronological narrative, which layers in the suggestion that all riddles will be answered with one closing knockout revelation.

A must for fans of pulpy crime pictures.

Maskell stars as the titular Bull in this violent thriller that can't decide whether it wants to be taken seriously or give audiences a bloody good ride.
