We're only three episodes into the eight episode season, so currently it's impossible to say.
This link contains an interview with the show's Executive Producers Tara Butters (@breadandbutters) and Michele Fazekas and thus contains major spoilers. Therefore, you probably shouldn't open it!! However, to give a summary of what's inside it.
Pros: The creators appear to have some idea of where they are going. They are trying to create a long, slow-unfolding mythology.
Cons: The last question from the interview:
Q: Was LOST an influence?
Tara: Absolutely. I don’t think you can do a
show like this without having some influence. I feel very strongly
that this show shouldn’t be more than 13 episodes a season, because my
favorite seasons of LOST were the shorter seasons because they could
be so much more.
Michele: When you’re building these continuous storyline
episodes, you can’t jump around, you have to sort of build them in
order. And if you change something back here, it sort of affects this.
So that’s why we really liked having a smaller number of episodes, so
you can really craft it and be smart about it. Versus just kind of
Given you specifically mentioned being disappointed by Lost in your question, maybe its influence is a bad sign!
At the very least, I would point out that if you're looking to get really sucked into a fun and engrossing series with a clear end, you should probably stick to one that has been out a while or completed its runtime!
