I have no interest in blu rays really. You can tell the sharp difference in say, Pixar films...but for a lot of stuff, Ive seen blu ray films on 55" LCD screens and it doesnt get me "more" into the film. VHS to dvd, now THAT was a leap. This doesnt feel like a leap. Some of the blu ray films are so bright, that and the lame blue plastic it comes it feels like an eye sore.
For practical reasons, how could I replace my nearly 1000 dvds I have? By the time I even attempted to(all the dvds that got released on blu ray, as a lot of the ones I have never will be turned to blu ray) a new format will have come out and I'd have to start again. I wish there was more of a consumer backlash against blu rays.
