(Since this is the most recent thread having to do with the GOUT) ....
Well, Paramount just released the original versions of the first six Star Trek films in a boxset on blu-ray and - with the exception of Wrath of Khan (which recieved an all out restoration and therefore had zero excuse not to look great) - it seems they seriously did a half-assed job. Undiscovered Country is the biggest offender, taken from a 1080i master.
Y'know, I've decided that with these big franchises the studios are going to keep going back to the well until it's bone dry because the vast majority of people picking up their releases are fans of the franchise first and movie fans second.
