Criterion is definitely good enough even as a small studio that their newer HD transfers of Kurosawa's films were borrowed in Japan for the Japanese releases.
Some of the films had no original negative but the new scans were done at 2K.
Cannot remember the exact titles i think it was Toho who used the US masters. They did the same for Godzilla, which i think is horrible as the us release is junk in comparison to the new prints they were running in theaters for the anniversary release.
As for the oot the metaphor i see is like the original movies except this time the evil empire won, and the rebellion aka oot fans lost.
Once again the true fans of the real star wars trilogy circa 1977-1983 are screwed. Lucas excuse this time "its an oxymoron" to restore the films.
Its not an oxymoron more like Moronic not to restore and release what people want.
