The issue isn’t the number of seasons, it’s the abrupt cancellation of unresolved stories. 3 seasons is plenty. 2 seasons is fine. Hell, Chernobyl is one of the greatest pieces of media ever produced and that’s a mini-series. Just commit to giving the creators a chance to resolve their story. If that means a truncated final season, so be it. It builds consumer trust, and it increases the value of the back catalog. When I subscribe to a streaming service, a show that was cancelled on a cliffhanger offers me literally zero value. I’m not interested in starting a show that I know will never provide a satisfying conclusion.
