This is what I said at the New PQ thread at AVS:
I have only seen the US version. Pan's is the most disappointing BD movie purchase I might have made. The faces just look terrible. I daresay the worst looking faces out of my entire collection. At moments, sometimes the cheeks of the girl remind me of some topographical map or something. Bland whitish blotch, surrounded by a less whitish ring, so forth. I was really disappointed because I enjoyed this movie a lot.
However, I must say that sometimes my greatest disappointments come when my expectations are highest. *sigh*
It looks completely gross. Let alone unrealistic. The grain does get you more detail. Some movies that I think of with excellent detail, but with a lot of pronounced grain (to me), are Casino Royale and POTC II & III.
Some people think DNR exists because everyone wants their movies to look like a Pixar cartoon. After all, they wouldn't make the movies WORSE unless they thought we WANTED it. *shrugs* On one hand, the die hard grain enthusiasts wish that there was zero DNR, and left the choice of how much to add to the consumer with outboard devices. OTOH, others think that a touch of it here and there can be an acceptable compromise. None of the videophiles I respect like a lot of it.
Pan's Labyrinth has the worst DNR of faces that I've ever seen. What a shame. I basically lose respect for the PQ opinion of those who give this movie top marks in PQ. Just speaking perhaps a bit too candidly.
However, thanks for giving me the impetus to find out how much DNR was used before I might possibly purchase Dark City.
