Hello, Nameless One, welcome to E.
I actually got a lot of WTF with what's happening with Dany. A lot of the things that weren't supposed to happen... did. The death of Rakharo, the death of Irri (or was it Jhiqui?)... Doreah, at least, was not supposed to make it to Qarth as she was supposed to die during the crossing of the Red Waste before they reached Vaes Tolorro (which is a whole arc that was very diminished in the series), so that makes things even on that front at least.
Likewise for the visions. I'm actually disturbed... a LOT. None of the originals were kept, although I do like the one one with Drogo and Rhaego, that was a nice touch. But... the whole point of them...
They could at least include the vision of the Red Wedding. And, hum... no prophecy? Quite an important one, as far as later occurrences go.
The entire thing with Qhorin totally boggles my mind as to why change it so much. Anyway, I really laughed at Rattleshirt's: "You don't want this one coming after you."
The Others looked amazing, but honestly... if this lot found Sam, he wouldn't survive. Nor are they, apparently, in any way this organized.
The whole thing with Robb and Talissa and wedding for love. >.< In the book, at least, he wedded Jeyne for honor. Really bold changes to the characters. My brain is still stalled from Cersei trying to poison Tommen.
I think they really summed up Margery with the: "I want to be THE Queen." I'm looking forward to see the Queen of Thorns appear, hope she makes the cut.
She was great in the books and having her in puts a really grey area over who's behind what happens on Margery's wedding to Joff. I really hope they don't have Margery to plot all that herself.
And Jaqen did tell Arya that she stole three souls from the Red God, R'hllor earlier in the series and in the books as well. I think it doesn't pertain as much to Jaqen's belief as a faceless man (which he wasn't supposed to reveal, by the way), as it does to the fact that the cart he, Rorge and Biter were chained to was on fire, which is R'hllor's domain, which means he would have gotten the three of them if she didn't throw them the axe. Also, since Braavos and Asshai isn't that far apart, I'm willing to bet that this many-faced God of Death is the one that Melissandre calls "the one who must not be named." Thus, they are two sides of the same coin and to believe in one, you have to believe in the other as well.
Or maybe Jaqen is just suggesting that R'hllor might take those souls, if she somehow offers them.
Given how Thoros of Myr repeatedly revived Beric Dondarrion whilst serving to R'hllor, I wouldn't be too surprised.
Too bad they couldn't keep the same actor for Jaqen, I think he did an excellent job.
All in all, I keep thinking that these books didn't deserve a show with a tight budget.
