My Pro's:
1. Arya Killing the Night King. It felt right to me. She spent the first 2/3's of the series training to fight and kill, and the god of death has been something she's talked about since season 1.
2. The battle itself. I thought it was awesome. Maybe a little bit less fog would have been nice, but that was awesome television.
3. Lyanna Mormount. If you're going to go out, go out like a boss stabbing a giant through the eye. I also thought they did a good job of not making that a focal point. Once it was over she pretty much got trampled. She was a really good character, but wasn't very significant. They did this one right.
My Con's:
1. The only war that matters really didn't. I realized awhile ago that the Azor Ahai prophecy wasn't going to matter, but basically the Night King and the long night didn't especially matter either.
2. They didn't kill anyone important.
3. There should have been 8 episodes this season, and they needed a 9th season. We don't have to go back over all of the reasons why this didn't happen, but this should have been the penultimate episode of this season.
4. The entire Three Eyed Raven storyline is done. That was a lot of build up, and I can't help but feel unsatisfied (yes, this is just my opinion) with it.

I was really looking forward to Howland Reed, and the drama he would bring regarding Jon's parentage. At this point though I seriously doubt that is brought in. The R+L=J storyline was the central mystery of the series, and it's been sidelined. At this point I think Daenerys wins the Iron Throne, and now I kind of want that to be the case. I hate when any story has an extremely abrupted change of direction with no development. Trying to do the Aegon Targaryen storyline in 3 episodes has a very high chance of being lame.
