Mondstadt has a huge area that's out of reach in the beginning, and even now is completely deserted, Stormterror's Lair is a hundred times what the other regions would like to have.
Li Yue was attacked by a giant sea beast, it's cool!
Had not impact whatsoever on anything, it was all in a cut scene. The change was one useless building (if cool because it flies) being unavailable for a while.
Inazuma was supposed to be inaccessible due to a massive storm.
It was a black screen.
And was plunged into civil war.
Which was an even shorter cut scenes and nothing else, anywhere.
Was Mondstadt good? No.
Did literally nothing happen in two regions and well over a year? Yes.
The entire event was about Kazuha's great grandpa and... tangentially Scaramouche, which yet again appears for two seconds in an event, with no explanation. I'm not going to forgive "it's a set up" for the FOURTH time in a row, for the SAME CHARACTER.
Put up or shut up, and Genshin is really good at talking, not at delivering anything of value.
And yes, I do not care one bit about anyone in Inazuma. I know their clan stuff is important. I also care 0% about any of them, Ayato in particular is the worst and most useless character in the game when Ayaka in already here.
What's the fucking point of having them deal with corruption, the Shogun, their ancestors fuckery... if nothing happens? From the very first time we set foot in Inazuma, nothing has changed. Raiden drank some dango milk and now she's chill, so no biggie, the bad guys that were corrupt... well they're still here, but now it's the son instead of the evil dad that's in charge. People that appeared in one quest, and not before, nor after.
Everything that happens in Genshin is just here to say "we did it and then we won and the villain is defeated but wait-", while revealing nothing before, during and after, everything's resolved in two seconds, look at the utter shite that was Sangonomiya, I can only call that a joke. And Kokomi is just as worthless.
Hell, Enkanomiya was the best part in ages because it was actual fantasy! And revealed stuff about the world, and the past! Even the event had far, far more relevance than Ayato, Yae, or Kazuha could ever hope to be. The reptilians ARE interesting. The latest fuckery of the noble family that has finally reclaimed their place but not really because the game has nothing to show for it? That's what we got. Raiden being a murderous asshole? Nothing happened.
Why did we even go to Inazuma? So that we can watch a cut scene of the antagonists furthering their plans.
If they want a story, they need a set up, and a pay off. They've shown none of that.
