We need a z-lib for movies, shows and music. Revive bittorrent (yes, i know it still exists but it simply doesn't have much content; not many people sharing/seeding anything but blockbusters) or, make a better bittorrent.
I usually can find what I look for, but it doesn't download because there are no seeders. For awful hollywood sequel movies there are 1000s of seeders, but when you look for something that isn't or wasn't a blockbuster (or popular anime), you will find it pretty much impossible to actually download it. I use rtorrent on a server and some things only come in after many months; some things simply never do.
The popular stuff will be available anyway; i'm more worried about the fringe stuff which gets removed (from netflix etc) for reasons of woke-ness etc.
