Remember when Cersei blew up the Sept and there was like no blowback.
Pretty sure she sat in that window and drank wine for 2 seasons
Yeah that was really dumb. Even though I felt like it was a bit of a cop out and a lazy way to get rid of the High Sparrow and the Tyrells without having to actually explain any of their plotting, I actually really enjoyed that sequence from the Season 6 finale, and I disliked Cersei a lot less than the High Sparrow so actively rooted for her to beat them.
However Season 7 then starts and she's inexplicably the Queen for some reason, even though she has no actual legitimacy to claim the throne and we get no indication of anyone being opposed to it other than one lamp-shading throwaway line by Sam's dad long after the fact. I get that she takes it "by conquest" but it all happens off screen and we don't get to see a power struggle or any scheming or anything, unlike in Season 1 with Robert's death when both Ned and Renly actively try to prevent Joffrey's succession.
