I've actually never really read much Dredd comics except on wikipedia, but his design and every piece of art with him has always been just so bad ass and iconic. It just hits you.
I even kinda enjoyed the old Judge Dredd movie, thankfully I was mostly oblivious to how badly they fucked up the actual character. But, at least it still looked cool.
I'm pretty hopeful for the new movie, the original creators read the script and said it actually tries to be faithful to the comic, so that's something. At least they already confirmed that he will not be taking off his helmet, which is basic stuff right there. Helmet looks a bit big for my liking... but we'll see.
