FILM REVIEW OF ''FIGHTING WITH MY FAMILY''Although Dwayne ‘the Rock’ Johnson gets top billing in British writer & director Steven Merchants’ amusing but insightful wrestling biography “Fighting with My Family” (**** OUT OF ****), he spends most of its 108 minutes off screen. In other words, if you’re going to watch another of the Rock’s conventional action thrillers, you’re going to be sorely disappointed. Essentially, “Fighting with My Family” is the equivalent of a female version of “Rocky” (1976), and Merchant chronicles the rise of a female British wrestler, Saraya Knight (Florence Pugh of “Outlaw King”), who had dreamed since age 13 about breaking into the WWE.
