JMS had a plan with Babylon 5. He knew how to carry a series forward, figured out alternate plans in case of emergencies, and despite everything, people still remember it 25-30 years later.

Same with Sam Esmail and Mr. Robot. Or The Expanse, despite how many cancellations it got.

The only thing people remember Lost for is how much they fucked up the ending. Or BSG… fantastic series, terrible ending. Just wasted potential tarnishing their legacy.

At least, Vince Gilligan has a good track record.
