Query: Hi Def????

I rated this movie 5 star... I like this movie very much. I own both version DVD and the Blu Ray version.But what dissappoint me is the picture quality of the Blu Ray version. I do comparison between both format, absolutely no difference.So for them who Superman big fan who already own the DVD version, just save your money. Absolutely no worthy to own the Bluray version.
