Oh. It was so wonderful that I forgot to come back.
No, seriously, it was massively, massively better than the Stallone abomination. This one did brush over and largely ignore the horrible state of the larger world that Dredd lives in, there was no discussion of corruption or nepotism, though nobody seemed surprised when the corrupt Judges showed up to off Dredd and Anderson. I certainly got a small idea of what life in MegaCityOne is like, and it was properly horrible. Psy-Corps has been rebooted, though, and there was no mention of the Wastelands, and Mutants only got a very oblique reference, but nothing that was missing impaired the story. They left enough things open that they could very easily add and flesh out the rest of the Dredd universe(s) without too much disruption. This movie was the greater whole, in microcosm.
I have no complaints, really, though I do agree that the Slo-Mo effects were a bit overused. I was waiting for someone on that to display enhanced reaction time or SOMETHING that made it relevant and not effects pron, but it never happened. They also seem to have done some odd things to colors when they were adding 3D effects, and those didn't work too well.
All in all, I would watch it again, and I wouldn't mind seeing a sequel, as long as it's going to break more ground, as opposed to providing the same material again with some small plot details changed.
Siglessness is boring.
