still don't think lucifer deserved saving after such a shitshow of a season. it was like csi miami with a tiny little sprinkle of supernatural. probably the least interesting of all dctv shows.
on reddit and twitter people were talking about what abc owns of the shadowhunters. and what they own is very little, and it's been used for the show. the author sold those rights because she needed the money, but apparently she's a bitter bitch and it's very unlikely she'll sell the rights to anything else. so it's not like abc has much more of a story to tell. anything else they'd do for s4 onwards would be non canon, which could make the book fans leave the show
