Okay so why is it good? Demise is a non-character Akuma ripoff who appears at the very end to announce that he will reincarnate for all eternity because he's angry.
Well, there is some kind of "good" deity with Hylia, it makes sense to have a "bad" deity with Demise. I actually liked Calamity Ganon in BOTW to be more of a... "natural disaster" than a "conscient" being. It changes, it's something different. Oh i would love a new really cool villain like Yuga but for this one time, it works for me.
What is enriching about that, as opposed to the power of The Legend of Zelda being a myth retold again and again for new generations, with variations? It's just fan-fiction lore wank. "Ganon reappears again because Demise sez so", box checked, we now have a Logical Reason for Ganon to keep reappearing because apparently we needed that, despite the fact that this reason is not inherently interesting or enriching at all. I don't give a fuck about Demise. Skyward Sword is all tell and no show. If you're gonna build up a villain, BUILD UP A VILLAIN.
Too bad you didn't liked Skyward Sword, wasn't my case.
That being said you said something interesting about the fact "Legend of Zelda should have been a myth retord again and again for new generations, with varation". I actually find that even dumber and the result is Twilight Princess with those "big" every protagonist here without murch purpose... Having a very cool Zelda and Ganondorf design wise but.. Nothing else somehow. Maybe i could tell that this game is all show and no tell ? Ah ah.
Well, i hate that, i prefer having them reincarne that "very evil deity" in whatever they seem fit for the next episode. It make sense for the narrative even if it downplay something you loved and they are still free to do anything they want. Works for me.
And anyway, contrary to popular belief, nearly every main Zelda game was made as a follow up/prequel to another episode. From A Link To the Past to Ocarina of Time and Wind Waker. Handlet games are the real exception here. Oh, of course, i don't think they really thought of a big chronology like today at the time... But it still never was about "a myth being retold" even if a lot of people would have preferred that.
Zelda being a mortal incarnation of Hylia is maybe even dumber. We had a reason for Link, Zelda and Ganon to be important, and that's because they're inheritors of the Triforce. Okay so now Ganon is Demise, Zelda is Hylia, but Link is just a schmuck with courage, shouldn't he then also be some kind of God to be worthy of the Triforce, since Ganon and Zelda both got their Totally Awesome Lore-Filled Backstories? And if not, why not?
Maybe that deity is the player ? I mean without him, that guy always lose somehow.
Oh well, not really important anyway. I don't think reincarnation is less dumb than "inheritor of the triforce". You just like the later better because it was here before.
I'm really glad BOTW completely resisted the temptation to insert more meta-lore, if nothing else.
Actually, it's the only thing we agree.
For exemple, I actually loved how they managed to tell that "Fi" exists and even talk to Zelda (given her "researcher" motivation they actually go well together) but never show any actual dialog from Fi in the game which would have been totally lame and inelegant in my opinion.
Everything was kinda subtle and it's good for guys who loved Skyward Sword like me or guys who hated it like you.
