The reason so many US series are cancelled, and not just Netflix ones, is simply that there are too many of them. Producers discovered that most series attracts more viewers during their first episodes, then numbers start either exploding if the series is deemed to become a huge success, or slowly fading year after year. Therefore they already know that cancelling a series to replace it with a new one after some strong advertising will without any doubt pay in the short time. How could they solve the problem without leaving watchers with unresolved plots and those awful cliffhangers? To me there are two possible solutions: either produce less series so that they're not competing against themselves, or offer by contract a way to resolve plots by guaranteeing that a certain number of episodes will be produced anyway after the cancellation decision. I don't see why implementing either, or even both, could be detrimental in any way to the business, unless they're counting profits by the cent with total disregard to their customers.
