I didn't say they would kill it. What makes you think, Amazon for instance couldn't push forward with a second season and do a good job? I've found, Amazon productions to be generally superior to, Netflix. "Jack Ryan" come to mind. Netflix however did a great job with "House of Cards" for instance. So maybe "The Passage" can be saved, no?
Maybe even the cable channels HBO, Starz, Showtime, etc.) could have a look? I enjoyed season one FWIW.
