Subverted expectations - coming from the show that killed its 'main character' in the first season. Understandbly bitter, but nothing out of the ordinary for GoT

Largely for me it’s because the undead arc was the arc I was most interested in. The politics and maneuvering for the Iron Throne I grew bored of, so no longer have much interest in the outcome of who claims it. Means I have very little excitement for the season end. Kinda weird.

It just doesn't feel quite right that Arya, who never had anything to do with the goings-on beyond the wall, was the one to strike the blow. While it brought her arc to a satisfying conclusion, it came at the expense of 7 and a half seasons of Jon's arc being built up.

Compare prior shocking developments - Ned's execution, Edmure's wedding, the Green Trial - those events all came as the logical conclusion of the mistakes and/or ambitions of those involved. With Jon barely playing a part in the War for the Dawn, his arc is aborted.
