As you said, EW quests weren't anything special but they were quite inoffensive and often manages to be amusing in their own right. That's a low bar to get past.
I haven't done all of them yet, but it's a case of "I see what they're trying to do," just told in the worst way possible. They're trying to use them to flesh out Tural, but they're just not good.
For example, the Weaver/LW/Carpenter one is about the Turali language. There's an interesting hook here - the alphabet and the language itself is based on the Eorzean one, and so it's a borrowed language. You get a bit of backstory into how this was chosen specifically because it would not privilege any one of Tural's tribes over the others (once more hinting at a far-more-interesting world of culture than we actually got). The course of the vignette is that there's a... server? at the local
restaurant taco dispensery, who is told a lot of stories and as such is effectively an oratory storyteller. You work with the crafting vendor to transcribe these stories, which are mostly the mythos of the various tribes.
Sounds good, right? Nothing stellar, but an interesting little tidbit. In abstract, it really should be. And yet it's so plodding and slow and stupid, everything is explained to you as if you are literally an adolescent, and stupid contrivances continue to get introduced in the course of the vignette that make no sense and seem to contradict other aspects of the story. Every single step, the character stares at the camera and slowly explains what the moral of the story they just told was, and everyone goes "yes, this will make Tural so cool."
Another one is clearly supposed to provide more detail into Vieran culture, and specifically how the Turali tribes differ from the ones in... Dalmasca or whatever. Another seeks to explain the divide between what is effectively an artisan caste and everyday merchants, but they're all told in the most awful and offputting ways. Bad humor, annoying tropes, constant reiteration of extremely-obvious themes - the DT special.
