Netflix orders a final 'season' of 'The Killing'

"The Killing" — which was roughed up by critics but, worse, not exactly embraced by viewers, either — is coming back for one final "season," a fourth, Netflix just announced.

The company said it was ordered a fourth and final one, comprised of six episodes, and that this will serve as a "conclusion" to the first three seasons. Plus this: Only Netflix subscribers will get to see it, not AMC ones.

 "The Killing" was actually revived the last time as part of a unique cost-sharing deal between AMC and Netflix. But no mention of AMC this time.

No word on arrival date or casting, but it's inconceivable that either Joel Kinnaman, who is attached to the next "RoboCop" (heck, he IS the next RoboCop), or Mireille Enos won't be the core of this final lap.

 Meanwhile, this question: If this does well by Netflix' calculus, should we rule out a fifth "season?"
