Right from the prelude, it pulls you into its gaping maw. The sound design in said prelude alludes to something enormous. It's terrifying.
From here, we go off-grid into the highlands of full episodes. Our guide, Professor Ryan, carefully explains an event of some magnitude has forever altered the landscape of earth. Careful attention has been allotted to the sound of Ryan: it is EQ'd to sound as if it blasts from a speaker which has fallen prey to oxidation.
The semi-found-footage format works very well here. These snippets are dangled strategically to leave the audience grasping for more.
The sound design and foley work is EXACTLY what I like: realism. So, admittedly, I'm biased. But, I found their approach appropriate for this story and it betrays a cunning behind the curtain; these guys thought this out.
It's always a challenge to review shows whilst avoiding spoilers. I shall just say that the episodes masterfully pull you in by dropping sufficient clues and curiosities at a perfect pace.
Beware this show if you've no time to binge an entire season.
It's that good.
