Dredd is a really ****ing good movie, and you should go see it.
For those of you about to burst out with an "I AM THE LEUUUUWW": Everything the Stallone movie ****ed up was gotten perfect here.
But what really gets me, and this is kind of surprising to be saying about this class of movie, is that it's actually very tightly plotted. Details are not done for cool or throwaway. They matter. Anderson is a psychic: not only is this used frequently, it's actually important to the plot. The multiple fire modes of the Lawbringer pistol are shown off, but each in an appropriate situation, each done well, and it feels natural that they'd be used where they are. The fact that the pistols are encoded to DNA is set up early, but it also pays off by saving Anderson's life. The slo-mo shots are not only given a story reason to exist (how many ****ing times can you say that?), the movie is very careful to use them only when that reason is in effect.
This is easily the best action movie I've seen this year. (EDIT FROM THE FUTURE: Looking back, it's probably the best one I've seen in the last five years.) Go see it.
