I don't purchase movies anymore but I could see myself going to a store to rent a 4K blu-ray to get the commentary tracks. Those are hard to come by online.
That's one of the things that kills me about present day distribution. There is such a massive hole in not getting to hear from the creators the way you could with DVDs. Shows like The Simpsons, etc. have offered a massive amount of information presented through commentary, that wouldn't otherwise be known.
When I was a kid I'd watch Futurama on DVD with commentary and think "Wow I bet one day I'll be able to pause any movie and click on anything and get all the info about it." I can't believe we went the opposite direction.
This is one thing Amazon does well. Pause almost anything and it will show you the actors presently on screen (with headshots, which you can click on to get more info.
I guess the other side of that coin is I feel like we have more access to creators than ever with youtube and podcasts. If I want to "meet my heroes" so to speak, I don't need DVD extras, I can just watch them in all sorts of formats online. Pre internet, you couldn't really watch Scorcese on hot ones.
