Watched it on Friday but wanted to think on it before posting.
I feel they finished it well to the point this could be the true end of the series or open for continuation down the line. While books 7-9 have some character differences, anyone who wants to know what happens next could easily start from book 7 and get a conclusion.
Glad they remained book faithful regards ending the Inaros arc, a moment i'd been dying to see all season on screen.
Think it's been mentioned but if you watch to the end credits, there is a hint of something within the ring space gate.
If they do carry on, i'm not sure on the casting for Duarte, starkly different to my mental image but that's just a personal thing.
Definately a gaping hole in sci-fi viewing again, I don't have patience for 'passable' sci-fi anymore - may just continue with my BSG rewatch.
Finally - credit to Dominique Tipper, there are some excellent subtleties with her acting, I despise Naomi as a character but she wasn't very likable in the book either so she's carried that well. Also apparently 'that' scream was a spur of the moment thing and caught them all off guard in the last episode.
