This is my biggest concern with anybody (not just Amazon) trying to extend Stargate SG-1. I want more Stargate. Not a sudden dystopian nightmare, or dour bleak exploration of this or that, or gutting Stargate to write some other show wearing Stargate on the outside (e.g., "It's Game of Thrones, but Stargate!").
It's not even that those things are bad. I've watched and enjoyed some of them. It's just that I know where to get them and I've got enough of them right now.
This is the main reason I’ve been watching Star Trek TNG recently. If anyone could recommend some vaguely optimistic sci-fi books that would be amazing.
