I'm in the don't have an issue camp. They seem fine to me and as others have mentioned, very much like a 70mm theater experience. I'll go with it being a settings issue also.

That said, I do have one qualifier to my view on any home release and maybe this is also what some people are mistaking for Bluray looking wrong. If the film has been cleansed of grain or had the contrast & color pushed, it looks bad to me in general. Bluray makes it even worse. It could be that the studio made the film look wrong, not the player or the TV.
