Really brilliant show. I got hooked on it immediately and watched the whole thing inside of two days. I am a bit worried about how they'll follow it up as I got the sense from reading behind the scenes details that season one was meant to be much more of a closed story and that it was the producers that suggested the ending should be a bit more open ended. I'm trying to take it for what it is and not buy into any of the mystery boxes they're setting up for later seasons.
