Magic teleportation my biggest bugbear, and the whole 'go capture a wight' plot was dealt with really badly. I'm sure they could have come up with something better to get a similar end result.
My random thoughts on the final
As we watched, said to my wife it was very out of character for Euron to just walk away like that. but didn't think much more of it. In hindsight, his plan should have been obvious
Enjoyed watching the Starks take down Littlefinger. I'm glad they showed that Sansa and Arya obviously had conversations with Bran off screen, rather than have him just sit around being a wierdo talking to noone.
Although I do find it strange that Bran won't tell Arya or Sansa about Jon's parentage - but blurts it out to Sam, who he has barely met, within 5 minutes of him teleporting in.
And Sam is a filthy liar. He never read about Rhaegar's annulment. He got it all from Gilly. Don't go stealing her credit Samwell.
Also - Jon Snow's real name is Aegon Targaryen, and he is a half brother to Aegon Targaryen. That wouldn't be confusing if everyone had lived.
And the image we got of Rhaegar looked a little bit weedy, and not a fearsome warrior
