This sub has a megathread that has a list of trusted sites for general use and specific categories. It also has sites for direct download if you prefer it
I've already took a look at it bu on my phone it gets muddy. I have to take a break and sit at the computer to go in peth into all the information there.
I just use the qbittorrent "search" feature. Add some of the search plugins for different sites that you can find when you open the search options.
*Arrs are nicer, but a lot to setup imo. qbittorrent you just download, open it when you need it, and then you're done with it. If you don't torrent a lot, it's more time-efficient.
Usenet and the Servarr apps will cover any movies or tv shows you want to watch. I use Jellyfin to stream it to my TV, and Jellyseer for finding shows to watch.
You can run it all on your PC via Docker, or on a NAS if you have one. You can even set up Jellyfin to delete media you’ve already watched, so the whole process is pretty much automated besides telling it the shows you want with Jellyseer.
Also, use the Trash guides to set up the Servarr apps. This is a must.
