The initial appeal of Netflix when it first launched almost a decade ago was that it really did have EVERYTHING you could want. If it was still in print here in the US, you could rent a physical copy or watch it on the streaming platform. Of course that isn't the case nowadays, but Netflix is still the only place where you can find some great shows. Including some fantastic anime.
Streaming has basically changed everything about television, but anime has been hit most noticeably by it. Everything down to the way seasons are constructed and watched have changed so dramatically that any attempts to cling to the old way of ordering and producing shows (see Black Clover among others) are met with immediate and vehement denial.
Netflix has changed the way we watch anime, so the anime it features on its site as exclusives had better be pretty damn good. Fortunately, that is definitely the case more often than not. Sure, there are some REAL stinkers in there, but there are more than enough anime in Netflix's library of exclusives that prove to be classics in the making.
