HBO is in an interesting place. I actually did sign up just to watch Game of Thrones, and also to finally watch Westworld and maybe they're betting that they have enough for people to watch to actually continue their subscriptions. I mean, I decided to keep the service for about 3 or 4 months including the 2 that it'll take for Game of Thrones to finish up, but there's not denying that HBO actually does have quite a catalog.

That said, after 4 months, I doubt there will be much to interest me anymore, and even if there were, I could always just watch it next year when the next season of Game of Thrones comes out.

That said, if they offered $60/year, I would probably keep it around for a few years rather than paying between $20-$40 once a year.
