Just saw it today. I'm giving it a "Good" vote. I can't go higher because I think the Stallone version is better. (waits for the screaming to die down...) That's just the way I see it. I liked the production design better, the music, Diane Lane over Olivia Thirlby...and I can't get overly exercised about the no helmet thing since my only experience with the comic version of Dredd is Heavy Metal covers by Simon Bisley.
Still, didn't hate this. It took a while to get going but I liked it once Peachtrees was shut down and it became "Escape From Peachtrees" (didn't see The Raid, so I can't compare...) Anderson's character arc was typical of any kind of rookie cop movie, aside from the mind-reading, Lena Heady plays a great psycho-bitch, and Karl Urban is good as Dredd, but not as intimidating as I would have liked.
