Remember when there used to be scenes where people spoke like real people? Where they connected on a human level? That's all gone now. We go from major plot point to major plot point and anything that doesn't tie into the endgame is cut. That's not the storytelling the show was once built on. There used to be time to talk about a brother dying but now there's no time so Rickon is forgotten.
This isn't about showing a boat floating across the narrow sea, it's about showing things down so these characters feel like people again.
Yeah a lot of the drama in the show would be resolved if the characters actually talked to each other. But conversations that you imagine would happen, just never usually happen.
Both Sansa and Arya told each other that they had long stories, and you would assume that at some point since coming back, they decided to share those stories with each other. And Sansa would have revealed that she was held hostage in King's Landing, and how terrible the Lannisters treated her. Especially since Arya has talked about killing Lannisters on her list, and they could have bonded over that, thus shutting out any attempt by Littlefinger to make Sansa look like a Lannister sympathizer.
But the way it's played, it's as if Sansa and Arya never spoke to each other beyond a few sentences since she returned. This has happened a lot since season 5, conversations not occurring in the weeks, months that characters have been around each other.
I'm still miffed that Meera and Sansa never had a scene together to talk about their fathers, their dead brothers, and a scene where Sansa could have honored Meera before the lords for being a hero and returning a Stark back to Winterfell.
