Story-wise, Season Five offers considerable variety; “The Daedalus Variations” is heady sci-fi filled with technical mumbo-jumbo about parallel universes, while “Whispers” is a zombie jamboree straight out of Night of the Living Dead, and Vegas, an “alternate reality episode” in which Lt. Col. John Sheppard (Joe Flanigan, in what is still the show’s most appealing role) plays a beleaguered homicide detective, takes place almost entirely in that city. As usual, the best stories are the ones involving the Wraith, including “The Queen,” in which Teyla temporarily transforms into one of those villainous creatures. Also as usual, the visual effects are first-rate, and the bonus material is copious (including commentaries for every episode and all manner of featurettes) and impressive. If this is indeed the end of Stargate Atlantis as a series (a feature-length movie is already in production), it will certainly be missed--but at least they’re quitting while they’re ahead. --Sam Graham
