Great cast, well shot, but at times the script is as dumb as a bag of rocks.
Dialogue can be a little too on the nose. Scenes play out because they'll look cool rather than make logical sense. Plot is basically: gangsta arranges meeting with rivals, kills rivals, then walks away in broad daylight as if nothing had happened. Rinse and repeat.
Predictably the two main black characters are murdered before the final act. Given the material they were having to work with that might be considered mercy killings.
Overall: if you're willing to switch off your critical faculties and lean into 100 minutes of shootouts and swearing, King of New York could become a bit of a guilty pleasure.
