I would say that my only things to pick with what I’ve seen of Legacy are as follows:

The grain reduction. I prefer 35mm grain over the negative, and even when he’s using 35mm prints, he’s reducing the grain to achieve a near negative medium.
The opening crawl. After I saw the crawl preview on his vimeo, I just thought, Why would you do that? I mean, the crawl losing detail as it goes further up the frame is the natural fade into black. He even said that he doesn’t want to change anything internally, and I would say that is doing exactly that.

Other than these nitpicks, I am really liking how the previews look, aside from the color grading of course, and I am looking forward to more news.
