OK guys, you've probably already seen this but I thought I'd repost here, since I think that, although it would be quite inexplicable, it may actually be an intentional change, because it's only the soldiers that are totally blurred and not the AT-ATs:

It's a comparison between the Blu-Ray and a 35mm scan of the original version. The Blu-Ray fails miserably.

Maybe they were trying to conceal the AT-ATs' feet being hazy by making it appear that there was actually a misty haze on the ground level? Because it does look less like the AT-ATs are floating in the air.

That's an ugly one, it's like that on the 2004 DVD as well, the same blurry mess and loss of detail is also seen on other sequences in the battle, here's a few examples before that one. I don't have a 35mm scan to show the difference but even the motion-smeared '97SE TB demonstrate the difference.

The detail doesn't matter, as long as we get rid of all the grain. ;)
