SEASON PREMIERE: This excellent crime series, starring Idris Elba as intense investigator John Luther, has been dormant for five years. But now, thank goodness, it’s back, and it arrives with a surprise: Ruth Wilson, who played sexy killer Alice Morgan, is back as well. And that’s a surprise, because we last saw her character at the end of Season 3 in 2013. When Season 4 began, she and John Luther had gotten together and broken apart (all of it out of sight of TV audiences), and he spent much of Season 4 mourning her death. But, as it happens, she’s very much alive. And their sexual attraction and odd dynamic may seem more familiar now, thanks to the subsequent character interplay between killer and investigator in Killing Eve. For a full review, see David Hinckley's All Along the Watchtower.
