If it were 8x05 and this were the vibe, I would agree, and it does look as if Dany's getting the "loser's edit," but it's early days yet. Emilia said in one of her interviews that she has to give a speech in several languages in S8. Dany has accomplished a lot in the past with speeches. I'm not convinced that all this early hostility from Sam, Sansa, and the Northerners isn't just setting the stage for a dramatic reversal of the kind Dany has successfully engineered in the past with the Unsullied, the Dothraki, and pretty much all her naysayers. Davos said you have to earn the Northerners' respect, which suggests that Dany will indeed earn it, and that hard-won respect will mean much more than if the Northerners had just fallen at her feet from the first meeting. Hopefully she doesn't have to lose her armies and her dragons to the AOTD before the Northerners decide she's worth a damn.
Dany's big Unsullied moment was in 3x04, not 3x01. Her big Dothraki moments were in 1x10 and 6x04. Let's give her a few episodes before we write her queenship off as a lost cause.
There are several stills from that 8x02 scene with Sansa and Dany in the library that suggest that although things start off frosty, they warm up to each other. There are several shots of Sansa standing and looking down at someone (Dany) with a smug, cold expression, but there is one still of Dany from the same scene of Dany sitting down, smiling warmly, and looking at someone who is also sitting down judging from the eyeline. It might be assuming a lot, but I think while Sansa starts off nasty and smirky, she ends up bonding with Dany. And if Dany wins Sansa over, that's huge.
