I am one of those people who was not thrilled with Danny's story arc. In hindsight, all the signs were there, I just thought she turned it up to eleven too quickly, if that makes any sense. Because of that, I was pleasantly surprised when they killed her off so early in the episode. At that point, I became really curious about what was going to happen, and what followed was pretty satisfying. Maybe not in a "they tied up every loose end" or a "this is Season 1-4 caliber" kind of way, but I felt like the remaining characters all ended up where they were supposed to. It was strangely hopeful... Maybe too hopeful, but I personally needed it after the complete bummer that was Season 8.
Overall, I think that Game of Thrones is an amazing achievement. Its first four seasons were mind-blowing. The next couple were good but, in my opinion, a tad dull. And it's last two have been the equivalent of a podcast on 1.5x speed. I really wish they stuck around for nine or ten full seasons, but I guess everything ends sometime. A week or two ago, I was genuinely concerned that I would never want to revisit the show again, but I'm already looking forward to rewatching it a few years from now. Can't believe it's over, but glad I was along for the ride!
