Heavy, in regards to your Predator question, yes work was done on Predator, but Fox issued strict instructions that detail was not to be sacrificed to eliminate grain. You're also looking at a modern film scan rather than one that was done about 4 generations of scanner ago which certainly helps. Movie still doesn't look great though, but from the people who have seen it, it's..."better".

Unlike most here, I have already watched the disc. Or, at least, the first 20 minutes of it, which was all I could take.

The opening credits scene with the helicopters flying in and the team riding in jeeps is a wash. It looked like crap on the old Blu-ray (barely a DVD upscale level of detail), and it looks like a different form of crap here. There's no net gain or loss there.

However, for the rest of the movie after the titles, the actors definitely look like plastic on the new disc. When the action moves to the jungle, the folliage is so smeared that it looks like motion interpolation has been turned on or something.

The old disc is inconsistent, but looks like a grainy movie. The new one just looks weird and not at all like film. It's a travesty, IMO.
