Something that bothered me in the trailer was the new background in the Hoth trench scene. It might be because I'm not used to it, but it felt fake, like it was too much in focus or because there was too much grain.

Here's a comparison, with the last pic having a blurred background.

I completely agree. I mentioned this a while ago, but no one replied. The new background looks a bit too "flat" (should have some more shadows) and should be more blurred. Otherwise, its a great way to restore continuity.
