Hello folks, I thought I would resurrect this thread. I have been watching every episode from the Lost Complete Collection and wanted to discuss the SQ and PQ. I'm finishing season six and I'm noticing the PQ is horrible. I see raised and inconsistent black levels, lots of noise/film grain I am not sure, and a really ugly grainy blue cast in some dark shadow areas. It's as if they had to rush out season six to blu-ray and didn't spend time on the mastering, I don't know. I think season two has the best combination of PQ and SQ (as well as story/plot). As many know season 3 was the first season of lost to make it on blu-ray. Audio was PCM 5.1 for season 3 and 4. I was disappointed that ABC kept the PCM audio for the Complete Collection, I wish they re-encoded for DTS-MA to match audio on seasons 1, 2, 5, and 6. Also seasons 1, 2, 5, and 6 have a well functioning Season Play mode that accepts multiple user names, but seasons 3 and 4 (the first two seasons released on blu-ray) have a poorly executed version of Season Play that's buggy and never works for me. Again I wish ABC re-encuded the menus and Java to upgrade the Season Play for those two seasons to match the others. I'm sure I'm not the only one who double-dipped with the Complete Collection since I already owned seasons 1,2,3,4, and 5 on blu-ray and seasons 1 and 2 on DVD. Even with these technical problems I think Lost is the best TV series ever made, and the beauty of Hawaii (and many of the cast) is a perfect match for Blu-Ray.
