Call me ignorant or whatever, but I don’t see the benefit of 4K for these movies. They are old movies that, whether we all like it or not, will always look like old movies. They were filmed on old medium, and meant to be viewed on a theater screen shot from a projector. Not on a tv screen from a 4K UHD Blu-ray player. No matter how many pixels you cram into it, it will always look like grainy film from the 70’s, so what’s the point. If 720 doesn’t look any better than 1080 (by what Ady says), why would 4K look any better?
If you are seriously worried that it doesnt look great blown up at 4,000+ pixels, then I think you are missing the point of the Star Wars films. I understand you want them to look their best, but I personally think what Ady is doing is making them the best they can ever be and if you really want 4K, I’m sure there will be plenty of people who will upscale it.
But that’s just my own personal feeling on it.
