Sharing a basic plot outline with “The Raid: Redemption,” the worst movie of 2012 to date, isn’t a good starting point for the dreadful “Dredd 3D,” which plays like the world’s uncoolest video game. In its dystopian future America, “judges” (cops who make on-the-spot determinations of guilt and impose and execute the prescribed sentences) patrol Mega City One, an 800-mile megalopolis from Boston to D.C. Greatest among equals is Judge Dredd (of the 1995 Sly Stallone bomb, “played” this time by Karl Urban behind a mask that makes Tom Hardy’s in “The Dark Knight Rises” look positively commodious).
