• “Dredd 3D” is a meat grinder of a flick that assaults the audience’s sensory organs with wave after wave of mayhem, death and gratuitousness. This is a movie that aspires to the ne plus ultra of rated R, possessing qualities that will surely enshrine it as a cult favorite but damn it for those who want more than full-fledged viscerality. Forget the Stallone version from 1995: “Dredd 3D” is the true heir to its comic book source. Judge
