Dredd. It was awfully awesome. But only if you like ridiculously awful movies like I do. No plot, Judge Dredd never takes off his helmet, token cute blonde girl, pretty much only one set, criminal underbelly, explosions, and awful script. It basically felt like the first mission in a FPS video game. However, Karl Urban also played John Grimm in Doom, Vaako in Riddick, a "gritty" Pocahontas-like film with no dialogue, and other such things so...y'know.
It's kinda his thing.
