I thought the first 30 mins were great, mostly because of the quality of acting. You really got a sense that Dany had lost all sense of introspection (i.e. sanity), that Tyrion was racked with guilt and that Jon was in turmoil. Up to the stabbing it was played out perfectly.
But then we had that scene at the Dragon Pit - easily the worst scene in the whole saga. Painfully embrassing. Were they trying to be funny? "How about democracy?"...gaffaw! I can't get my head around just how cheesy that was. And Bran the Broken? I recall and interview with GRRM where he said that it is wrong to change somethign just because too many have predicted it (mainly in reference to R+L=J), and that doing so would be cheap and cheating the audience. Well, that's just what D&D did here; they picked the guy that thew fewest people expected to be made king, rather than goign somethign which made sense in the story. And Sansa saying "Yeah North is gonna go free" and everyone being "Yeah that's fine, we'll happily fall in line but you go it alone, no issue with that at all...". Christ, it's like they coudln't even be bothered to finish wiritng that conversation!
After that it just got stupid. "Yeah, Jon, thanks for saving everyone over and over again. Now fuck off back to the Wall because the Unsullied - who are buggering off anyway - said so". Would've been much better if he'd exiled himself out of grief. And that Council meeting; again, bad comedy, like the crap you get in Marvel films trying to force a laugh.
Also, something I noticed yesterday as Tyrion was being led to the cells - all the Unsullied soldiers had knobs! Couldn't miss it - one was like Bowie in Labyrinth . Aren't they all supposed to be eunuchs, root and stem?
