Grain gives the movie it's cinematic look. Now, can there be times that the grain level is too much? absolutely. Zach Snyder is a guy that uses a ton of film grain. Most directors use a thin layer of it, so it doesn't look overtly digital. Especially in movies that use a ton of CGI. Removing all the grain from older movies with CGI, makes the older graphics stick out like a sore thumb. Watch Aliens, when Ripley is confronting the Queen, the shot of her burning the eggs, the CGI background looks really bad and dated. Grain can help offset that look a bit.
RoboCop 4k had a great 4k restoration done to it. Arrow Video did a great job. Which Dracula are you referring to? the Gary Oldman one? I haven't watched that on 4k yet, so can't comment.
Last of Mohicans is one of my all-time favs. I wouldn't want that to look digital at all. It's a period piece movie. The grain gives a perfect look. I do hope Mann will be working on a 4k restoration soon. Give us both the Directors cut and theatrical cut. I prefer the theatrical.
