Why pay someone else to run a service that you'd have been paying Netflix for.
That's how I feel about Usenet tbh. If you're going to pay, actually pay to support the shows you're watching. IMO.
Otherwise you build a server PC and set it up for the *arr suite, Radarr, Sonarr and the rest. It's the cost of your internet and your electricity after the upfront cost of your server.
Bonus: you have it when your internet is down, since they're downloaded to the hard drive.
