Also, the end of S1 is a total cop-out IMO.

Agreed. Apart from just being kinda so-so and cliched and a Marvel-style sensory assault that assumes emotional arcs are completed by stabbing and shooting things, it reeked of "You have to renew us because the story's nowhere near done!" That's understandable as a business move by people whom Netflix will happily fuck over, but it's bad storytelling when you know perfectly well that Netflix might fuck you over, and history has shown it won't be effective either, due to the aforementioned over-fucking.
