Doctor Who: The End of Time, Part One on BBC America at 9 p.m. Your last chance (sniff) to see the fabulous David Tennant as the Doctor before Matt Smith takes over. This two parter is also the last Doctor Who written by Russell T Davies. Guest stars include John Simm, Bernard Cribbins, and Catherine Tate. (The second part of the miniseries airs Jan. 2.)
