I didn't know there was another Blu-ray edition of The Killer. It doesn't seem to be the greatest but at least it has no DNR and isn't badly converted from PAL.
The DD Blu-ray uses the same source as the German EMS DVD but crops it a bit and scrubs out detail. This is what they did with their Hard Boiled transfer, but I can't remember which transfer that was based on. At least they didn't screw it up like they did for The Killer.
Their HB DVD was the first way I saw the film, and it is the best all around version as of now. The Blu-ray is a nice bump up to HD that reveals more of the re-done transfer's limitations. But I still think some of the color timing is off.
I now own the Fortune Star and Criterion editions of both in addition to the DD Hard Boiled and I'm still not at all satisfied with any of them. These are the two films Criterion really needs to get back in the collection.
