It depends on the movie. If it is a newer, shot on digital type movie, then that is rather large. If it's one that was originally shot on film and has been "remastered", that is perfectly fine. Film grain makes all the difference. Most movies these days are completely flat, unless the company creates noise to mimick grain.
