Finished this a week or two ago. Pretty good! But I have to say (spoilery, though not incredibly)...
...the voiceover early on was not only needless, but actively undercut a lot of the revelations that came later. One or two of the revelations, in particular, would've been much harder to guess, except the narration primes you to start thinking in those terms early on. And it seems to give away this surprise without any corresponding benefit. The show is pretty twisty and turny, so perhaps they figured it would help situate people better...but I don't think it did. To whatever degree it is difficult to follow, it's because of the sheer number of characters, not the concept itself, so telling people the general nature of what's coming doesn't help.
Moreover, if they hadn't tipped their hand, the surprise would've been particularly delightful, because it would've been surprising without being unfair. That's the balancing act with any revelation: it has to surprise you and feel like something you should have figured out, or at least something that seems obvious once you know about it. In this case, it would've seemed more surprising than it was because the show "feels" like dramatic horror, and not sci-fi, even though there's nothing that says sci-fi can't be shot the way this is shot, or emphasize the kinds of character work this show emphasizes. It would've turned our preconceptions about the aesthetics of each genre against us, which is completely fair.
Anyway, good show, but definitely a bit missed opportunity there.
After a couple of episodes, my wife and I started to wonder how on earth something like this could continue past one season (if it is indeed renewed), but obviously it goes in some pretty bold places near the end that make that possibility a lot easier to imagine. Definitely hoping for a renewal.
