When it first came to prominence, I said that Blu-Ray was not going to supplant DVD in terms of the average movie viewing experience. I still stand by that, but the truth of the matter is that I have bought a handful of Blu-Ray movies since then, and have in some cases willingly sought them out. I have some very strict criteria for what gets bought on Blu-Ray, though.
1) Nothing older than 2008 will be bought on Blu-Ray unless it’s remastered, out of print otherwise, or offers some benefit over a DVD copy besides picture quality. Anything older than about 2008 probably wasn’t filmed with any kind of HD resolution in mind, and so it’s pointless to waste the money in order to see high-resolution film grain.
2) No TV series will EVER be bought on Blu-Ray. This is so I have the option of ripping the series to my iPhone or iPad and watching it in a mobile environment.
3) The only movies I’ll buy on Blu-Ray are ones where the visual effects are strong enough to necessitate the high quality. So far that’s been Inception, Summer Wars, and the new Star Trek. The Rebuild of Evangelion movies get a pass due to the CG and the fact that they’re the tinkered-with re-release versions and not the theatrical ones.
4) When possible, buy them used. This is just common sense.
The sole exception to the rules has been the ROD boxed set, but even that grudgingly fits Rule 1 because Aniplex decided not to release a DVD version. I only picked it up because I was able to get a decent deal on it, dropping it down to what the individual discs would go for on eBay. But it was still under protest.
I don’t think that the format has legs enough to completely supplant DVD. What I’m seeing more and more stores do, however, is scale back their physical media sections considerably owing to the fact that there are more people streaming stuff online, and owning a disc is seen increasingly as an oddity. Yeah, I do kind of hope that streaming catches on, but I still like the idea of having a physical disc on the very likely chance that contract squabbles take away a movie I want to see just before I want to stream it. Streaming services are too fragmented and volatile right now for me to entrust any of them with my sole desire to watch new movies and so forth. Maybe that’ll change, but I truly doubt it.
