It's so worth it. I spent many years pirating stuff manually by downloading the torrent file, adding it to my torrent program, unzipping it, and using a file browser to select game.of.thrones.s01e01.1080p.proper.webrip.whatever.fuckme.mkv. One day I was like fuck it, we'll do it live and I dove into the whole plex/sonarr/radarr/jackett thing and it streamlined the piracy problem to the point that I very rarely even have to do anything beyond opening up a web browser and typing the name of whatever I'd like to have added to plex and the rest just happens automatically.
It grabs only the torrents in the language you specify with exactly the bitrate and resolution you specify, it unzips stuff and puts it in a correctly named directory with organized filenames and grabs the movie posters and thumbnails. I almost never even have to log into my torrent site. I usually only go there so my account doesn't get disabled for not logging in frequently enough.
As a bonus sonarr and Radarr have a calendar page so you can see when the stuff you want is expected to air in the future.
Lemm.ee refugee here!
