Well, the music was certainly top-notch in my opinion. I love 'Footfalls' and have that playing in my car frequently. 'Close in the Distance' and 'Flow' carry a real emotional punch. And it was nice to get some context for 'Answers'

I very much enjoyed the transition into it too - the scenes as we approached Sharlayan for the first time.

The Grand Company of Eorzea gathering in Gyr Abania.

The 'Alphinaud makes a phonecall' scenario, where pretty much everyone we'd met on our journey (to that point) turned up in response.

The launch of the Ragnarok. That was just pure awesome. I mean, the music (Torn from the Heavens) and setting were fantastic, but seeing the Primals in their non- bastardized state, and at their full potential, made me smile no end!

The Soup scene at Camp Brokenglass, with Jullus

But what I loved most? Zenos' appearance toward the end. I loved that it was him of all people who came to our aid, despite his reason for doing so. I loved the fact that he actually took what Alisae said onboard. I loved the fact that the byproduct of his motivation to gain consent from the WoL to fight them once more helped save the universe.
I loved the fight against him too - he was a character I was pretty indifferent about to that point. However, when he addressed us - "not as the hero but as simply.... you" (not the exact dialogue, I know) it made me think how ironic it was that Zenos.... ZENOS of all people... was genuinely considering what we WANTED to do rather than what we HAD to do.
I loved how he referred to us as "simply..... you" and "Adventurer" too. It was certainly the first time anyone had referred to us as such for a long time.
And the fist fight with him at the end? I loved every second of that!

And finally I loved the closing montage, with the Ascians walking toward the Scions, and which ends with that moment pretty much everyone screenshots:

Such a touching moment, and it felt quite Meta too - like the Devs were acknowledging the player's part in getting the game to where it is.

I know Endwalker isn't popular with some, and have mixed feelings about it overall myself, but I still really did love the moments that I've mentioned.
