Thanks, I ordered the Alien Quadrilogy Blu Ray set.
The grain discussion raises a question in terms of what happens if a Blu Ray player is used to upscale a grainy 1080p to 4K. I would guess that upscaling to 4K might result in more pronounced grain which might look worse. I'm going to try it both ways.
If it doesn't get upscaled by the Bluray player, then the set will upscale it to 4K.
Which piece does the better job won't be known until its been done of course.
But both of those films aren't very pretty to begin with. Very dark and grainy, and Resurrection tends to be a bit oversaturated.
Enjoy the films..3 and 4 don't deserve the hate they get, just like Prometheus and Covenant surely don't.
