Not having seen the BRD of Terminator myself, I found the following review quite disappointing.

"The Special Edition release of this film had a few areas of noticeable grain and some issues with colors. I’m happy to report that the Blu-Ray release is jaw-dropping. Colors are accurate, so accurate that I sometimes wondered if I was watching a brand new release and not a film that is 22 years old. A majority of the grain has been cleared away giving the film’s setting and theme a more horrifying and terrifying feel ...."
The removal of film grain with means of DVNR is the least to be expected from a good HD transfer. I don't want a 22 year old film artificially popped up to "look like watching a brand new release".
Just look how wonderful unfiltered film grain can look on HD releases like "Apollo 13".
Or are they just afraid the MPEG-2 codec used could create compression artifacts when encoding grainy material at given limited bitrates? (BD 25)
