just because you are unhappy with the outcome of the situation
I’ve never seen this show. I’m probably never going to. Apparently I wouldn’t be getting a complete story anyway, and for reasons yooou have outlined, that aspect is the director’s fault. He had two seasons to tell a complete story. He did not. He did not, knowing full well Netflix doesn’t like doing third seasons. He did not, knowing his show was unusually expensive and complicated. He did not, knowing the viewership wasn’t about to skyrocket from the known figures for season one.
And for some reason you said he’s not to blame for the incomplete story he told.
Are you suggesting he’s an idiot? Because even idiots knew about Netflix’s two-season limit. It did not sneak up on him. It was tiredly predictable. It was, and remains, the most likely outcome for any Netflix series lucky enough to get a second season. No crystal ball is required for this basic pattern recognition. Sneer all you like; it is common knowledge.
Cliffhanger endings at the best of times are a frustrating gamble against cancellation. Creators are as responsible for them as they are for every the rest of their story.
