For me, they’re more trouble than they’re worth. For wanting to support your favorite artists, I’m rewarded with unskippable trailers and FBI warnings, and if you want to play Blurays on PC, well… Just take a look at this. Keydb files? BD+ decryption? What happened to just putting the stupid disc in the machine and hitting play?
With pirated movies and shows, I just double-click on a file and away I go. Why would I ever want to go back to Blurays?
I used to collect Blu-rays of my favorite films - buying them after watching elsewhere. It’s nice to have an actual physical copy of a thing you like, especially it’s some kind of special edition. But I haven’t even tried to play like 90% of them, because it’s too much of a hassle. Aside from the encryption there are also region restrictions. I have Blu-rays from all 3 regions and every blu-ray player sold locally will play only disks from its single region. So Blu-ray format tried very hard to stop me from buying and using it and, eventually, it succeeded.
