in regard to whether this is a movie or comic topic, well...Both. I'm a massive fan of the Dredd comics. I own most of the collected volumes now!
the film is so good though. I am biased as I love the universe already so to see it treated right is such a treat, but it's the best film of the year by a mile IMO. It's like seeing a super stylized, often beautiful and ultra-violent assault on precinct 13 starring everyone's favourite fascist. They said they put a huge amount of work into making the slo mo scenes look great and it really shows.
Also, the film serves as a pretty good introduction to Dredd, seen as it is a pretty normal day in his life. I find Dredd a super character as he's not an anti hero, he's often just a villain (in stories like 'America' he does some pretty awful things). Also the whole world and people of mega city one are superb fun. If anyone's a fan of graphic novels/comics and hasn't given Dredd a look, seriously, do!
PS Walter should have been in the film, amirite.
PPS for sceptical fans of the strip, John Wagner was a full time consultant on the film who said he thinks it's great, and many changes were made at his request to make it as faithful as possible. To sceptical viewers of the 1995 Stallone one...That just wasn't judge Dredd in the least. An amusing movie is the best i can say for it, but it's just a terrible abuse of the character. God knows how i'd feel if I was the 2000AD guys who'd put decades of work in and then that was how the world knew judge dredd for so long..
