Why we Love it: One of the brilliant things about "Doctor Who" is its ability to tell stories in a variety of genres. One week it can be sci-fi, the next period drama, then comedy, then horror. The Steven Moffat written "Blink" (based on his own short story) is just about as terrifying as any "Doctor Who" episode ever. It is the tale that introduces us to the Weeping Angels. Each subsequent appearance of these horrifying statue-like creatures who send their victims back in time would be slightly less scary until the almost comical "The Angels Take Manhattan," but here the Weeping Angels are at their most devastating and the Doctor isn't even really present to help the potential victims. Instead, he appears via Easter eggs in 17 different DVDs where he talks to the intended viewer, Sally Sparrow, who winds up having to fight the angels along with her friend, Larry (who transcribes the conversation for later use by the Doctor). The episode doesn't just introduce a truly scary evil, but unfolds via a great mechanic. It is "Doctor Who" and the Doctor at their most clever.
