《极斗4之暴杀令》故事讲述香港的家庭暴力和女性被侵犯事件，各人对事发的反应，当中有人选择以暴易暴，替天行道，其实为社会和法律不容，因为香港无蝙蝠侠，不可以执行私刑，其实电影带出社会问题令人反思。 《极斗3之雅博渡口》是「与神格斗」后，这次《极斗4之暴杀令》是「与仇恨格斗」，电影主题与性侵犯有关，并表明调子相当灰暗。“极斗4之暴杀令”有点像80年代经典电影【山狗】，山姆哥借电影致敬。
Erstwhile Special Forces operative Doc Alexander is asked to broker a truce with the Mexican drug cartel in secrecy. When Oklahoma Governor Richard Jeffs celebrates the execution of a high-ranking cartel member on TV, his Chief of Staff and Doc inform him about the peace he just ended. But it’s too late, as Cuco, the cartel’s hatchet man, has set his vengeful sights on Doc’s daughter Dixie. They don’t make ’em like Little Dixie anymore: honed to the bone, all gestures and actions, only a few words. Too many genre films these days try to create meaning by piling ideas and intentions on their narrative frames. John Swab, as always, works the other way around. Meaning and depth come from taking away whatever is superfluous – by reducing the plot to its bare essence and the characters to their core trades and tricks. Ultimately, Little Dixie feels like the pulp fiction version of a Giacometti sculpture, all fearful symmetries and mirror images. A gem of crime cinema at its purest and most philosophical, proudly featuring noir’s new darling, Frank Grillo.
