The movie had no plot, so many stupid parts of the movie. When Dredd killed the first of the 'rogue judges' he could of stolen his gun, but decided to run out of ammo instead in the next fight. durrr.
As well, anderson has the ability to read minds, yet she got surprised and her gun taken.
Besides small things like that, I feel as if the movie could of been better if they had focused on the apocalyptic setting rather than having a stupid cop vs drug lord battle the entire movie.
