Try Real Debrid. It’s rare to not find something. Should you really not be able to find them, then the news servers are where you should head next. Just about anything ever made is on nzb. You’ll need to pay some money and do a little learning, but the Usenet is pretty rad once you figure it out. It’s a lot easier now than it used to be too. They have clients that will search, download, unpack, and assemble, all at the click of a button. But like I said, Real-Debrid+Stremio+Torrentio is amazing.
