Just got round to watching the 2012 Dredd on DVD and really enjoyed it. Much better than the Stallone version years ago. Of course it does have the advantage of having Lena Headey as the main villain, who isn't only my favourite Sarah Connor (from Terminator: The Sarah Connor Chronicles) but also Cersei Lannister in Game of Thrones. Karl Urban as Dredd does an excellent job and, unlike Stallone, keeps his helmet on throughout the film - and looks suitably ruthless and hard.
Unlike Stallone's version, too, there is a down at heel grittiness about Mega City which makes the scale of crime much more credible. The Judges are only just managing to keep the lid on things - and their grasp is slipping. And the story is a good one, very much reminiscent of The Raid in an oblique way - with more lethal gunfire than even most of today's action films. Olivia Thirlby as rookie Judge Anderson, who has psychic talents, is excellent too, giving her role a toughness yet possible vulnerability.
The good news is that it looks likely, despite a lacklustre performance in the States, there will be a Dredd 2. I hope so.
