Well, it was kind of slow. I would have expected more than what I saw on screen. I would say a good Redbox rental. Karl Urban was good as the judge...but he would be a better Mitch Rapp.
If you like Judge Dredd, this is a much more faithful representation than the previous version. Extremely violent, some pretty graphic depictions of violence against women and innocents.
Bottom line, it's a graphics/effects driven bloodfest. Urban plays the role with wry humor and overall it was enjoyable..
