Movies

[Billm]

Is there a list of movies somewhere that has a rating as to the quality of the picture in movie? The reason I'm asking, I just purchased a Playstaion 3 and Sharp 42" LCD 1080p in order to watch HD movies. I'm running it with HDMI and it's at 1080p. I presently have 4 Blu Ray movies, Underworld Evolution, XXX, Pearl Harbor, and the Italian Job. Of those movies, Underworld has the best picture quality. It's exactly what I had wanted in buying HD equipment. Pearl Harbor is second, then XXX and last Italian Job. The Italian Job has aweful picture quality. It's almost unwatchable. XXX is good but you can still se some grain to it also. I really don't want to buy movies that don't look any better than a regular DVD. Is this normal that some movies are not as good as others? Thanks in a advance.
