"Shiner" is a gritty character-driven drama all about Caine as the title character; a shady, unsuccessful, aging British boxing promoter whose world begins to implode when he gambles everything on one fight featuring his son in the main event. The story in this B-flick becomes an overwrought mess as Caine's character becomes an overwrought mess, making Caine's performance the only reason for spending time with the film. Okay for Caine fans and passable stuff for all others. (C)
