Disney+ has a lot of great content to offer and will most likely get even better the longer it goes on. The most impactful original and brand-new show they have right now is "The Mandalorian." Set in the Star Wars universe it follows a bounty hunter and his adorable friend.
Outside of this show, however, is not much original content that is getting people talking. There are some shows in the coming future based in the Star Wars universe, and some behind the scenes looks at Disney's parks as well, but that can only go so far.
