I posted my initial thoughts last night, but the park felt more "alive" than it has for years. Part of that is that World Celebration just had a beautiful vibe and everyone in the park seemed in high spirits.
On reflection:
The show itself was good, not great. Not HEA levels of feels. But I don't have much negative to say about it. More watchable than EF, less problematic (from a viewing perspective) than Harmonious. The original songs are beautiful. And as others have said, a brilliant new version of One Little Spark in the post-show.
I think Epcot is as Epcot-y as it's been for years, which is lovely.
But I'd like the show to have just a little something MORE. It lacked a truly unique wow moment.
I think overall last night was the happiest I've felt at Epcot for years, though, and that means a lot.
