You have your grain and quality
When I spoke to James Cameron last month about the Avatar re-release, a bit of concern was raised when the director revealed that he personally supervised the Blu-Ray transfer of Aliens and voiced his plans for that (watch the video interview here). Fans immediately took to the message boards, squawking about how Cameron might de-grain to the picture, similar to the transfer we saw on Fox’s recent Predator release.
A look at the Blu-Ray transfer is in, via an AVS Forum member, and the comparisons to the DVD are astounding. Here are some screengrabs, Blu-Ray first, then DVD. More comparisons can be found here.
Fox’s Alien Blu collection arrives on October 26.
