Like yourself I actually like film grain, make you realise you are watching a celuloid film not some CGI digital re-creation, and am glad you can see it in alot of the shots. Unfortunately in certain areas (Tatooine segments on Star Wars, Hoth on Empire etc) they must have put the DVNR on it's highest setting, and I bet the film grain drove the DVNR software crazy creating a somewhat murky end result in some scenes....
I think some are confusing film grain with DVNR artifacts - we have both on display with these releases...
I'd still rather have these than the SE's any day of the week however.
