No.
AV Forums , DVD Forums and all the technical reviews have all complained about the softening of the image on the Skynet edition and it is something I noticed the second I put it on to play.
Although for extras - there is no comparison as the Skynet edition is way out in front , not least of all for including all 3 versions of the movie
I'll see if I can find some links.
AV Forums compares the UK and US Skynet Edition with the earlier release- clearly no contest when it comes to extras but :
"Lionsgate, distributors of the US Skynet edition have gone on record as stating that no DNR has been applied to this (US) release. Well, on the back of this testing I'm not sure I agree, there is clearly grain reduction, there is also some fine detail loss, no matter how slight, that cannot be attributed to anything else. There has clearly been a contrast change as colours and black levels are that much stronger and more vivid in the latest editions compared to the Optimum release. But it is also a fact that these Skynet editions are blistering pictures and it very depenRAB on where you fall in the DNR camp as to what you will see in the comparison pictures. In pure, absolute, terms the Optimum disc contains the finer print detail and can therefore be judged to win out over the newer editions with the US one next and the UK one bring up the rear."
Most negative reviews (as above) refer to digital noise reduction that removes the grain and whether that makes things look better is definitely one thing that splits Bluray buyers into 2 camps.
But get the US Blu of Spartacus to see how it can ruin a Bluray and the acclaimed restorer of that film Robert Harris who worked on it to restore the lost footage has slated the release in no uncertain terms.
Alternatively Psycho has been left alone much to the joy of film fans .
Check out Jason and The Argonauts or Clash of the Titans to see film grain as it should look
