Agreed Bingowings, Raiders does have the simple SW fun factor for sure. You know what I've never seen close encounters! Must rectify that soon.
CatBus, I think we kinda agree about GL setting out to be timeless. "Sure, you can avoid references to pop culture...use a classical score". This was exactly GL's intent of using JW and not say Led Zeppelin. In comparison, the 60s/70s folk influenced soundtrack to the proto-SW film 'Silent Running' is sooo badly dated it makes the film hard to watch for me.
And just because SW looks different to what's out now doesn't mean that dates it. Just that what's out now will soon date. As you said the over saturated visual eye-sore like films like 'The Kings Speech', 'Skyfall' etc will date very quickly. Digital Graders are just excited by their new toys and will learn to not tinker wih every shot til the faces are half orange/half blue in time. They'll realise that the rich, wam and realistic palettes of 70s and 80s films like SW, 'The Godfather' and 'Raiders' are infact timeless.
