I don’t really know plex, I tried some media players like it ages ago, but Stremio just recently.

Basically it has plugins that link it to databases of shows and their torrents, then the debrid service links those torrents to cached versions that can be downloaded from the debrid servers at high speed so you don’t have to actually wait for a torrent. I also do it behind a VPN because that can get you in trouble if you end up using a torrent.

The only issue I’ve had is occasionally shows will get hit with copyright strikes that the debrid services will honour in order to stay in business. Usually another torrent will take their place but then you have to search for it in the list. Still better than Netflix just saying “no results” or “here are similar shows”. No, Netflix, I do not want something similar to the show I was halfway through, I want that show specifically. They may be fungible to your algorithm, but not to my heart. Fuck you, Netflix.
