Dredd was good.
It was darker and edgier than the campy Stallone version, but that’s not necessarily a bad thing (unless you’ve an aversion to ultraviolence or gore, I suppose). One reason I think it worked a little better than the previous film* is that aside from the shorter in medias res intro, the whole thing takes place in a much smaller area (than the first film did). You see the world in the intro and outro, but instead of taking you into the Cursed Earth, and then all over the city, you really drill down into the seedy underbelly of Mega-City One.
And besides, any movie that even tries to hand-wave a reason for gratuitous cool-looking slow-mo action scenes can’t be all bad.
*Which I still liked, don’t get me wrong. It was so bad it’s good, instead of being legitimately good, is all.
