If you loved Maniac Cop, try Vigilante
A bridge between a film you've already seen and one most people haven't. Vigilante has roughly 4.7× fewer votes than Maniac Cop — it's a deeper cut, not a mainstream recommendation. Here's what they share, and what the second one does that the first one doesn't.
What they share
Both films are directed by William Lustig, and they both carry the raw mood tag, and they sit in Action / Crime territory. If that's the register that drew you to Maniac Cop, the second film will land in a comparable space — through a different lens.
What Vigilante is
Garbage-strewn sidewalk at dusk, a single broken doll’s head rolling against a sewer grate. A father’s evening shift interrupted by the policlinic’s gloved hands returning his wife’s bloody scarf. William Lustig’s urban nightmare where a man learns the law is just another set of handcuffs.
