I will get right to the point. A Netflix original should not end a season on a cliffhanger unless it has already gotten renewed. Cliffhangers are meant to build excitement while fans are awaiting a show’s return. If you do not have the assurance that more is on the way, then it is just an open ending left for viewers to contemplate for eternity. The OA’s second season and Spinning Out’s only season both end on cliffhangers, for example.
