I buy very few 4K discs because on my 60" screen I see very little difference in picture quality to regular Blu-rays. I now have the 4K 10C and doing a quick comparison I can see a very slight improvement in definition. Nevertheless I'm happy to have it and add my support to releases of classic...
If I want a disc I'll buy it regardless as to what any reviewer might say. The only opinion which matters is mine!
I saw THE TEN COMMANDMENTS on first release and as a young child it was the most wonderful and exciting cinematic experience ever.
