I'm a massive fan of 2000ad and still read the comic, and I agree. I saw this movie in the cinema on its release and loved it. Most 2000ad fans don't but I did.
Judge Dredd was a very underrated movie. Sly looks awesome here. Sly and Arnold didn't make violent films, they made movies with action. There is a big difference.
It's not at all underrated. In fact, there's three scenes in the whole movie that were decent. It was soo bad that they should've went back and immediately made the first script (before Stallone and the studio interviewed).
