The first episode, in the first series, I think does a great job of shocking you. For me, I enjoy that for the most part, the plots are plausible and not that far fetched. It doesn't require a huge leap of the imagination to get to scenarios that are outlined. Plus I think the special effects are fantastic in their subtlety.
