I own about 100 blu ray discs. I don't just buy any blu ray, but ones with high bit rates and that are rated as high quality visually. There is a big difference in transfer, with some blu rays not any better than SD, especially in some of the older movies. The studios are getting better in making a quality blu ray product. I will continue to buy high quality blu ray movies as I enjoy watching movies. An excellent blu ray movie can not be matched visually by SD or through streaming, IMHO, especially if you have had your HDTV professionally calibrated.
