Broken Aesop: It's hard for a good number of people to buy into this movie's message about the negative effects of violence when the majority of victims of said violence are horrible, rotten people who couldn't be talked down on top of the film never providing an effective alternative to violence.
Complete Monster: "Little" Lou Manzi of the original comic is a ravenously psychotic mob boss and Torture Technician who makes Cold-Blooded Torture his hobby. Since becoming the head of the boss twenty years before the story, Manzi keeps a man as a toy, torturing him in every conceivable way he can think of day in and day out till the man is nothing more than an armless, legless chunk of meat- only still alive and conscious. In present, he tries to get the man's partner back to be his victim as well by threatening his family and even his young children.
Misaimed Fandom: The film was meant to be a meditation on the ugliness of violence and how it negatively effects the people involved, even when it's justified. However, a good number of viewers genuinely enjoyed the violent scenes, which were supposed to be the most off-putting parts of the story, possibly because the victims tended to be really rotten people. For example, Todd in the Shadows put the Groin Attack from this film in his list of his favorite movie nut shots, saying it was the most satisfying ballbuster he'd ever seen in a film.
Ray of Hope Ending: As the main page comments show, not everyone sees it in the finished film, but the script ends with two words: "There's hope."
