Query: 300 Blu Ray

This review will not critique 300 the movie. Rather it will be a critique about the blu ray movie quality. This is not the first time I purchased a blu ray movie and was disappointed by the picture quality. For some reason, when this movie is played, there is a grain pattern throughout the whole picture. It really makes watching the movie a disappointment. I already owned 300 on DVD, so I expected the Blu ray to be a step up in picture quality. Very disappointed.
