I like EW's story. It was fun and had really cool elements.
But just because it was enjoyable doesn't mean it was good, and Garlemald wasn't the only thing poorly executed. Right after we wrap up Garlemald, we go to the Moon for exactly 5 minutes before coming back home and see everything hit the fan.
People need to stop thinking that when people say "Endwalker is rushed" it means it's bad. It's not. It's rushed, that's what it is. Plot points and lore were rushed. A lot of things that could and should have been explored in Garlemald, especially after Werylt and Bozja, just got put on the backburner. We only speak to the aan for about 2 minutes before we have to deal with General Depresso. The Moon should have had more than just "Woo, mystery, Zodiark and... bunnies?". And we knew the Final Days were something we'd have to deal with, but there wasn't a slow burner at all. Even in the end, Meteion was trivialized, with the music not even caring about the meaning she has to the plot. For all his crap, even Necron's music theme had more gravitas.
It was enjoyable, and I'm probably one of the few who liked Hermes's incarnations. But it doesn't mean it's not without its flaws. One thing I loved going from SB to SHB was how there wasn't much unnecessary fluff in SHB, and even at its worst and slowest, it gave you a lot of insight about how that world worked and what would come next. In comes Endwalker, and we have... drunken Scions, Captain Depression, Rabbits!, End of the World? nah we have to build an airship, now with 10% more RABBITS! Or my personal favourite. "Our main characters are dying one by one? lol nah you know this is gonna end well, I mean how many times have we baited you with Flow and it never had major consequences since the first time?"
And unfortunately, these flaws wouldn't have felt so major and it wouldn't label the expansion as "rushed" if they gave each chapter its proper time to breathe.
