Old school eh? I haven't used those in a long time.
qBittorrent has search built into it, but search is better with the 'arrs.
Jellyseerr and the 'arrs make searching torrents as easy as browsing movies in a streaming service. Search and browse movies in Jellyseeer. Read about them, watch the trailer. Then click "Request" when you find a movie you want to watch. The 'arrs then automatically find the torrent, and download it using qBittorent, or one of those other programs you mentioned.
