Idris Elba returns as detective chief inspector John Luther — is that an incredible title or what? — in "Luther: The Fallen Sun," a thoroughly '90s crime thriller that couldn't be more '90s if it starred Ashley Judd and Morgan Freeman.
It's the kind of slick, reliable, chase-down-the-bad-guy detective procedural that was abundant in the '90s but was swallowed up as superhero extravaganzas began dominating our multiplexes. Even if it doesn't always work (and falls victim to an absurd climax), its beats are comforting and familiar, even for those who skipped the entirety of the series on which it is based.
Elba played Luther, the brilliant-minded detective whose obsessive nature sometimes results in brute manifestations of violence, for five seasons over nine years on the BBC. Here he's back and tracking down a psycho who is cyberstalking victims online and blackmailing and killing them in the real world.
