Currently writing a review on TotK. A short summary of my thoughts is that it builds upon BotW in nearly every way, and the verticality that is now present with the caves, the depths, the sky islands, and the vehicles makes it so that I'm never bored traversing. I think the story helps you feel a bit more present within it, whereas BotW was just [here's thing that happened 100 years ago], like that is still a thing but it's actually engaging because you are genuinely learning things as you uncover the geoglyphs, unlike BotW where it was "okay well all these characters are gonna die anyways."
On second thought, why was TotK said to be darker than BotW? After near-fully playing through the game, I don't think that's the case at all. BotW is about avenging your best friends in a post-apocalyptic world where no one recognizes you and everyone knows you failed. TotK has you explore a world you've now saved that is slowly but surely rebuilding, and it's a more traditional story of good guy vs. bad guy rather than good guy vs. the vague concept of pure evil.

I will say that I think, whenever DLC comes out, a playable Zelda needs to be top priority. Across two games, she's spent 10,100 years waiting for Link to save her. Let the poor girl swing a sword. It'd be cool as hell. Playable Ganondorf would be awesome as well, maybe in a side story about how he led the Gerudo army against Hyrule before he joined them, kinda like how the FFXV DLC handled alternate storylines and playable characters. My other hopes for DLC are expansions to the dream home system, more shrines (and tougher ones too, like in Champion's Ballad), improvements to the Sage ability activation (just give them Revali-style activations instead of having to walk up to them and press A two times), and lastly, Trial of the Sword, which is really weird that they don't have in this game since there were several Eventide-style shrines.
