And he's made zero movement in moving along the story. As best as I can tell, the whole realm should be in utter and complete chaos right now. The Lannisters are still loyal the Iron Throne, natch, and I guess the Freys, too, but Dorne is obviously not too friendly and the Tyrells have to be pretty pissy about the whole situation. The whole North is upset and once again the Greyjoys decided that they're their own kings. And Stannis still thinks that he's the true king and is kicking around somewhere around the Wall. In other words.... he basically brought the resolution of the story back to where it was at the end of the what... first book? second book?

We must be reading different books. The same place as where we were in book 1 or 2? Let's see.....
SPOILER ALERT
The North: House Stark has been wiped out as a political/royal entity. Winterfell has been burned down. There is no "North" anymore, just Bolton & his nutball kid running around skinning people with the Greyjoys hold a duchy or two that were loyal to the Starks. Most of the lesser houses have been decimated and are leaderless.
The Vale: "Ruled" by a sick kid who's being poisoned by his guardian.
Riverrun: Lost, taken over by the Lannisters.
Lannisters: Also swirling down the drain. Tywin's dead, Cersei's in prison, Tyrion's in exile for killing Dad, and Jamie seems to be moving toward saying "f it" to the whole thing.
Iron Islands: King "accidentally" died. Coincidentally, crazy ambitious son with a taste for magic shows up just then, beats out all contenders for the throne & send his brother east to snatch Dany, all the while attacking Westeros.
Kings Landing: Cersei's rule was a debacle. For one thing, she's going insane. For another, she surrounded herself with incompetents or seeming incompetents who had their own agendas. A religious cult has stepped into the leaderless void, arresting both Cersei (Queen Regent) & Margaery (Queen) for a variety of sins. The guy Cersei hired to take over the navy has split with all of the ships.
None of these (& there are more) situations are remotely close to where they were two books ago. The realm
is in chaos - it just doesn't know it yet.
And the other dangling plotlines that he has out there... Robert's bastards? Has moved about 1/1,000 of an inch since Book 1. The whole intrigue about who tried to murder Bran with the assassin? Hasn't moved. If that merchant guy cares that Dany sold all of his ships to buy soldiers? No mention. How, exactly, people are coming back from the dead? No answer. And how Arya went from so willful to just becoming a little altar girl while Sansa did a 180 the other way? No exposition.
Roberts' bastards already served their purposes - they all look like him & his "trueborn" kids with Cersei didn't. That's what got Arryn & Ned killed. That's not to say that Gendry or one of the others don't have a further part to play.We already know who tried to murder Bran, who set it up, and why. That thread was resolved by book 3.
I'm not sure what you mean about Dany. She didn't sell ships to get her army, she took the army herself.
I thought the coming-back-from-the-dead was explained pretty well by Thoros to Arya in either book 2 or book 3.
As for Arya, do you realize what she's doing? "Little altar girl" is the furthest thing from it.
And Sansa's arc has been going on since book one - there's been plenty of exposition on her growth.
