Yeah, no, that didn't work for me at all. I was one who was rooting for Jamie's arc. I didn't need him to be a knight in shining armor, just struggling and making (mostly) reasonable decisions.
I'm very much on-board with that AV Club article. (Thanks, Jett, for linking it!) I haven't read this far in the books, but even for me, the rape felt gratuitous and...just...why? I felt dirty watching it. I intensely dislike Cersei, but, honestly, I don't think I can overlook it, no matter what they do with Jamie now. For me, he's got the whiff of irredeemable about him. And it just didn't have to go there.
