Despite the show messing up themes and character arcs (#neverforgetstannis), would you say they’ve done okay with Jaime by showing that he’s not on a redemption quest?

I think they’ve leaned too far away from that angle, because now we have a Jaime who has conspicuously ignored Cersei crossing over what ought to be huge red lines for his character: she used wildfire to murder thousands of people, she tortures people to death for her pleasure, she’s acting increasingly paranoid and sees only enemies around her, and of course, she doesn’t care that their children are dead except as an attack on her to be avenged.
