They got rid of artifacts in Indiana Jones trilogy that nobody complained about. There is no original indiana jones trilogy dotcom site.
For some Reason when Bob Z did the release for Back to the Future on DVD and blu ray however he refused to have the noticeable things like wires holding up marty mcly painted out. These things hurt willful suspension of disbelief. I was recently watching superman II or III cannot remember which and the wires were so noticeable because of the cleanup job they did on the DVD, the fact that a fan with some off the shelf software could do it makes the studios lazyness pretty transparent.
They could offer 2 versions of the movies one with things like matte lines and garbage mattes, wires removed, and no story content changed or major changes done, something i don't care about, i did not return my Indiana jones set for being false advertising because the snake reflection was gone in the well of souls.
As for me i don't care if nothing else is touched but i don't want to see big black boxes around the tie fighters in star wars, in the gunport sequence. Even on a properly calibrated tv on the 2004 they are embarrassingly noticeable at 480P just wait until they hit in 1080P, the bitchfest will commence i can almost guarantee it, unless Lucas convinces them its a part of his original vision, or a deliberate creative decision.
