I mean, why not? It is convenient, and to me, really well priced for what you get. There's lots of things that offer far worse value for money that we don't really think about.

And I host my own Plex server with Sonarr, Radarr, etc. But sometimes, you just want to jump into something, and TV series can take a huge amount of space.

I don't know why Netflix is considered so morally repugnant, when they do still offer a good service for the money.

Convenience is worth something to a lot of people.
