I liked it, but I think it's leaning too much on the JJ Abrams mystery box thing where there's a lot of mystery set up that pulls you in, but the creator probably doesn't have it all planned out so a lot of it won't be addressed or poorly addressed down the line.
An understandable concern. Best path they could take is to ignore the "mystery" and just make it a character driven show.
This sounds like.... it sounds like the Quake soundtrack
I definitely hear it. Makes me want to play more Quake.
