Yeah that'll be hard. So much of the world is already explained. If they need to have new twists and surprises, it could turn into a LOST clone.I'm worried about it for sure. Its going to be completely different, but in truth we know nothing about the wider world that this is set in, so there's still lots of surprises possible.
I'm just going in with an open mind, not expecting/ hoping they'll go one way with it.
