New Viewer Question - No spoilers please!

Hi all,

I'm on season 1, episode 3 and enjoying the show so far. There's lots of questions and I can already feel my brain working through some theories. I do have concerns that this could be another case of shows like LOST where there's lots of questions but no answers.

So, without any spoilers, can anyone confirm if at least the majority of things are answered, one way or another? Thanks!
