Dredd.
At first I thought this was going to be Dredd as it should be done, but it while it was true enough to the source material, it was really just an action movie shoot 'em up with little real SFnal angles. The way in which they redesigned the costumes and urban setting for the twenty-first century was quite clever (and must have made it easier to film) but that robbed it of the frisson you get with proper SF and often had with the Dredd comics.
The other thing is that the comics were the product of a generation obsessed with Americana as it was viewed from the far side of the Alantic. That era is long gone now, and the movie reflected. It also showed up that Dredd the character is barely one-dimensional (but the woman who played Anderson did it pretty well, I thought).
So, not a bad effort at all, just. . . not really what it said on the tin.
