I’d go the other way. Apple TV+ is a great app in terms of UX. Perhaps, in some aspects, the best streaming app there is. But the service lacks enough compelling content because Apple insists on producing all its own shows, and the quality is hit and miss.
So I’d argue the solution is for Apple to start buying in content from other producers, in addition to their own exclusives. After all, even Disney+ carries a lot of non-Disney content to bulk up their appeal.
