I haven't seen this disc yet, but have heard good things about it. Gary at DVD Beaver compares it very favorably against the DVD release. But his screen shots reveal that, once again, Sony dropped the ball. The entire Harpy sequence in the Greek ruins, as well as an earlier sequence in which Jason is taken to speak to the Gods, were supposed to have taken place at night, and a day-for-night appearance resulting from lower f-stops was intended. Whoever oversaw production of the Criterion laser disc of the movie saw that these sequences had been improperly reproduced for video since the initial VHS presentation, and the two sequences had always before been trabsferred as though they were daylight sequences. Criterion darkened them down and the result was a revelation. Unfortunately, no subsequent video releases, including this new Blu-ray, has reflected the intent of the filmmakers. I was really hoping for a definitive version of JASON, but it looks like it may not happen now. (In addition to the corrected appearance of the night scenes, the Criterion laser included a solo Ray Harryhausen commentary track that has not been carried over to any subsequent discs (the Blu-ray contains a new track by Harryhausen....thank God at least we don't have to suffer through all of his rather misguided attempts to promote the colorizing of his earlier work during this track!).
