One thing I've noticed...is there's not a whole lot of difference between the Blu-ray and the DVD when it's played on a Blu-ray player. When I play the DVD on the standard DVD player, the difference is like night and day.
I have a sneaking suspicion that WB wants to sell NODS twice. If this version is successful, I suspect they will follow it up with the restored cut. Look at Watchmen. It was followed by the DIRECTOR'S CUT. I got suckered into buying that, because that was checkmated by THE ULITMATE CUT. There have been other examples of this sort of maneuvering to get people to buy multiple copies of movies. I might be naive and overly hopeful with regard to this matter, but I can't help but suspect that greed is at work here.
