QuoteThe problem with that is that the whole production has adopted a realistic look - set against that background the uniform has to make sense. I'd guess that a large part of that decision is budget, coupled with a desire to use practical sets over CGI (a very futuristic MC-1 setting would be expensive to realise with physical sets, dressing and costuming - a more near-contemporary urban dystopia more achievable), and to some extent to emulate the path followed by the Batman franchise. The latter point bleeds over into a need to distance itself visually and thus tonally from the '90's camp of its immediate predecessor, just as Batman Begins did.
Going the realistic route could be an inspired move by the producers or a huge mistake. It is a risk because it's hard to know if fans and your average film goer will prefer a realistic, gritty version of Judge Dredd.
The big difference between Batman and Dredd is Mega-City 1 is a city of the future and Gotham is a city of the present. The Batman franchise has to stay rooted in the present so the world it depicts can't be too over-the-top but Judge Dredd is set in the future and, in theory, anything is possible. If Batman used a teleportation device or dimension jump fans would think that is too extreme but that technology is available in Dredd's world.
Psi power is featured in the Dredd screenplay so that helps to make it feel like a sci-fi world.
