Only thing that's really going bug me, is that if Jon is wandering north of the Wall and they don't include Ghost somehow I'm going to be pissed. I get all the reasons they've avoided using Ghost in the show, but based on the entire character development Jon going into the wild without him is completely un fathomable. Even if they just put some blurry white streaks taking out enemies I'll be a little satisfied, but at least acknowledge that Jon has his own big, badass companion creature.
