I’ve read the books. I’ve not watched much of the series. From my perspective, it’s not Jon Snow who is the very important Stark family member. Bran, on the other hand, is the one to watch.
Bran is/will be important, but he can’t do it all by himself. And there are fewer Children of the Forest to help out this time, too.
>>Bran, on the other hand, is the one to watch.<<
Absolutely. He’s much more powerful than Bloodraven, and will use the weirwoods and beasts of the world as a massive tool to help. He’s been able to see the past, present, and future through the trees. My bet is that he’s the one that communicate’s Jon’s parentage to him through the trees - having seen Rhaegar and Lyanna get married in a godswood.
Bloodraven told him he’d be able to fly...and there are three wily & untamed dragons that need some discipline...hahaha
