Man, I can only request that you actually see the transfers yourself, and not rely on posted screencaps or online opinions. You could rent the discs for very little and settle the doubt once and for all. I stand by my review here - I did not see a mess of DNR at all. And on BTTF3, I went through various sequences looking for it - like the DeLorean/Train sequence, and I saw both grain and additional detail in the shots. Things certainly varied, depending on the amount of VFX work used in the shots, but I was never taken out of the sequence because of PQ. The closing shot of Doc and Clara floating off on the hoverboard doesn't hold up that well, but this is due to it being an obvious bluescreen shot that the Blu-ray mercilessly reveals.
