I agree it was better when it was all super mysterious. And I know a lot of people have given up on the show because it can be frustrating. But trust me, there are still many many millions of devoted fans who will be sad to see the show end. Myself included.

I think that expecting an answer for every single question is a bit ridiculous though. It's still a rather mysterious show, and if they decided they wanted to tell us every single little thing, that ruin part of what makes it special.
