Before watching the movie:
I expect this movie to be a lot like RoboCop. A police state dystopia set in the near future that is now both uncomfortably dated and also overly optimistic about technological advances.
I’m not sure if Dredd is a satire or just a warning, but I know the point of him is that the degree of force he and other law enforcement are allowed to use is meant to be far beyond excessive. I don’t know if that carried through into the movie, or into fan understanding of the comic or the movie. Starship Troopers is mostly loved for the hyperviolence it was meant to be satirizing, and I wouldn’t be surprised if the same happened to Dredd.
