The first is amusing in that you can see the same bits of redressed scenery in several scenes, because the redressing wasn't enough. Bits of that movie work, but it's very shiny shiny 1990s. The point about MC-1, bar in the early days, was that it looked like a jewel from the air, but a disaster when you were up close.
The newer one was a lot more 'five minutes into the future', but I liked it a lot. Mind you, I like grimy sci-fi, and Dredd was very much that.
