I'm not sure that I would be willing to pay for it separately. It has some good shows but not an astounding amount.
The interface is hot garbage that tries to upsell additional pay-for content and streaming services like Starz. Unless you know what you're looking for and go in with surgical precision, you get bogged down in a morass of upcharges.
They also started intermixing free-with-ads content and making it difficult to distinguish. My kid has started a couple movies only to get lambasted with ads every 15 mins and becoming thoroughly upset.
