Yeah, but the old Predator Blu-Ray is pretty bad too, so when I showed it to my dad, he liked the new version better. In the particular image you posted above, Chainsawash, there actually is no extra detail in the old version image, just a lot of extra grain. Make no mistake, I'd take the old version over the new "wax figurines museum" one anytime, but to most people the new one seems better because they associate grain with analogue video artifacting rather than film and when there's no extra detail to point out to them, they'll just thing it's basically the same image, just without a layer of grain.
One of the really good examples I saw is the Gladiator. The old BD version had heavy DVNR, while the new version doesn't and is, well, new, so it's got a lot more detail than the old one at first glance. It is especially visible on hair and stuff like that.
