There’s nothing like stumbling onto a new show without having been over-prepared by the media. It’s a nearly extinct experience these days, to see something about which you know almost nothing. I watched the first four episodes of “Orphan Black” that BBC America sent to critics without having been exposed to any ads or having looked into the show. I was ignorant and blissful.
I loved the experience, as the story line unfolded with a few juicy twists that took me by surprise. But how can I convey my enthusiasm here for this BBC America drama without spoiling the experience for you? Sigh. So let’s just say that I will not give away central plot points of “Orphan Black,” which premieres Saturday night at 9 after the return of “Doctor Who,” while I try to do some justice to the outline of the show.
