“Muzzle: City Of Wolves” (*1/2 out of four) was a desultory sequel to the 2023 action thriller about grizzled ex-cop Jake Muzzle (Aaron Eckhart) whose peaceful life of serene retirement is disrupted when a gang brutally attacks his family and he has to fight various inner demons to pursue them and take them down at any and all personal cost. Formulaic and routine thriller haphazardly put together out of the spare parts of hundreds of other (and better) cop movies. Eckhart is solid as usual but is himself “muzzled” by film’s unpleasantness and rambling tone.
