Once upon a time I consumed content by keeping video files in folders and watching them with VLC. Then I subscribed to Netflix. Now I'm back to keeping files in folders, except now I have Plex to give me the convenience.
I still have Netflix (free with my mobile provider), Disney+ (free with my Internet provider) and Hulu (got Black Friday deal for $1 per month).
Don’t really watch anything on any of those streaming services though.
Join a good IRC network - I use Abjects. Subscribe to the shows and movies you want to automatically download, one of their bots sends you files as they are posted. Write a script to copy them to the appropriate folder that Plex monitors.
