As we just saw the marathon a couple of weeks ago I haven't been all the way through them yet. I did check out the tank chase from LC cranked to 11 on the theater system and compared it side by side with the HDTV broadcast. It is stunning - the audio is so much richer, with fantastic use of the surrounds, and the picture is equally mind-blowingly good. The bits of Raiders I checked are so good it's scary. Gorgeous, grainy 4k scan with meticulous attention to the colour timing and dynamic range captured. No latter-day revision of the pallette, no attempt to make it punchy looking like modern blockbusters. Pay attention Kathleen Kennedy, THIS is how you present a classic series - now go to it with your other property please.
I also checked out the documentaries, specifically the making-ofs. I think I've figured out one of the biggest problems with KotCS: Speilberg didn't play seemingly at all on that film. In each of the three others he's constantly "making it up as he goes" - he's inventive, coming up with gags and moments on the fly as he's working. On CS it looks more like he shot each page as written, then moved on. I think the result is the not bad exactly, but listless stretches of Skull - there's very little inventive going on there.
Then of course, there's also the god-awful photography...my god KS looks terrible compared back to back with the original three:eek. I remember seeing some webisode where the 'Berg is talking about sitting down with Kaminski examining Doug Slocombe's photography for reference. The only way I'd believe that is if he had then added "...then we agreed to make this one look nothing like that. At all. In any way. We thought it would look cool if everything looked as if it had been shot greenscreen instead. Screw Doug Slocombe.".
