I suspect the bluray stuff is hype, when we're talking about releasing old shows that came out in the SD days. Aren't old TV shows just upscaled to HD with fancy filters? That's not the same as true HD content. But if you are a completionist fan of ST, bluray is for you. I'm sticking to watching it on Netflix for now. You don't have to fiddle with discs this way, and any episode is a few clicks away.
