Full polished web-apps to browse and select titles to download, automatically, which appear almost instantly in your plex/emby/jellyfin server, which give a superior UI for queuing up titles and tracking progress, that play on any and every device in your house. Full quality, (usually) the exact same bits, no DRM.
Here’s the killer - there is now a multitude of services that will do ALL of the above for you without having to lift a finger. They run the backend infra, put the media server on a 1 Gbps pipe in a datacenter, run a reverse proxy somewhere nearby that you have decent peering with, and it just works. If they have a large enough base of users, you hardly ever have to do the request step and just have a firehose of literally everything being released, plus the back catalogue of almost everything released on Bluray.
You basically have the dream of Netflix (aka Spotify for video) right now and it can cost as little as $10/mo. Share your media server just like your Netflix login with your friends and family even. It’ll spread just like that, and it’s impossible to compete against.
