Where are all the damn white walkers? They've had maybe 5 minutes of screen time across 4 seasons.
This is true in the books too though, you have to realize.
I'm somewhat salty about it, because one of the things that keeps pulling perspective on the reader was you'd cross a conversation, or a mention, or something weird shit that was obviously walker related in the midst of tons of political intrigue stuff. The reader gets this warped reality; you'd get so caught up in the machinations of about 20 different people, and who is fucking who, who just killed who, who took over what city, etc, that the white walker shit tends to be spectacular. Suddenly you remember "Wow, this shit is awesome but if these people don't get their fucking shit together those walkers are going to have them some fine dining."
Also, what they need to do is probably just go full on "Game of Thrones", an HBO made for tv series, adapted from the books and based on the works of GRRM.
One of the coolest things about the show (And I'll be honest, the Night's King shit was hella sweet) was seeing how accurately or coolly they managed to portray the character. Either, exactly in the way the reader envisioned, or possibly in a slightly different manner, but one that made absolute sense.
Now, going into these books, I'm going to already have the scene, the look of them in my head. As someone above mentioned, the imagery and the subtleties of the red wedding were what made it a total mind fuck. The show did not come close. Sweet as shit, but 1) Because it was such a mind fuck to begin with that the show was bringing up all those tinglies I remembered and 2) Because I got to see non book readers lose their effing shit.
The books are that god damn good because there are all these amazing subtleties. People just pop off shit left and right out of nowhere and suddenly someone is confessing to a murder, or outlining a crazy plot etc. That's how we find out about Olenna, and about Tywin's shit with the red wedding. I understand the show can't convey subtlety, but taking it away from book readers is just, icky.
Once my socks are knocked off they cannot be unknocked off, so to speak. The written form has, in just about every way been above and beyond the show. There are just things a series watcher is never going to understand. We knew going into joff's murder what motivation Olenna could have had. (We need a king, we just don't need Joffrey.) A lot of series watchers missed that. Some correctly guessed Olenna, but didn't sync up the fact that now Margaery was free to marry Tommen.
ANYWAYS, yea I'm a pussy. I like the way GRRM has of encapsulating a particular feel with just a few things. The red wedding was spectacular when he mentions that the rains of castamere was being played. Or when Catelyn feels chain mail. You knew INSTANTLY. In the show? They have to be far more obvious, she had to appear super scared, whereas in the book she remained calm until she was sure.
I have gotten up in arms about changes, but mainly it's brief. It's a bandaid; it gets pulled, I express regret that show watchers didn't get to experience that imagery as I did, or the scene as I did, but I get over it.
But now, if that scene comes up, I'll read it and still just be seeing everything HBO put there. It's like having someone finish a Rembrandt and even after you know how the artist wanted his work done all you can see is the shoddy work done to finish it faster.
I'll also say this: GRRM regularly throws in weird ass shit at the weirdest of times when you least expect it. That's harder to do on screen, but I cannot for the life of me understand why it was necessary to show us that now. HBO could easily have reminded us that the walkers are a threat still the same way GRRM did, with characters talking and guessing.
Full on confirming the Night's King was real, that he existed, that he still exists, that he is taking Craster's kids, that he is of a higher caste of walkers etc...that not only reveals something huge, but connects the dots in about 3 different ways, in a way dictated by the directors, NOT by the author.
Jimmies level is unbelievably rustled.
