“Bare Knuckle Brawler” (** out of four) was a pretty routine action melodrama about a cop (Pete Passaro) who returns home and finds himself in the midst of a murder investigation of two bare-knuckle fighters but the plot thickens when his brother (Jesse Kove) is murdered and he himself has to enter the world bare-knuckle fighting to uncover his killer and solve the murder. By-the-numbers story of underground fighting and organized crime; not bad but nothing terribly original. Martin Kove is amusingly cast as a martial instructs instructor and seems to be playing John Creese all over again. Danny Trejo glowers and mumbles his way through his umpteenth role as a crime boss.
