Black Doves, the highly-rated Keira Knightley spy thriller spent a week at #1 on Netflix’s Top 10 list and has already secured a second season. Now, it’s gracefully stepping down in favor of a new show at the top of the list, albeit a comedy special, not a scripted series.

You've finished watching Black Doves and are contemplating that ending, wondering what will become of Sam, Helen -- and the nanny -- in season 2. While you wait, there's another new-ish thriller that transports you across the pond and into several countries where there's so many close calls you may feel conflicted about whose side you're on.

The best new show to hit Netflix in a while has arrived with perfect scores from critics, but it may not be for everyone, given its subject matter.

In Netflix's spy thriller "Black Doves" Keira Knightly stars as Helen Webb a wife, mother and covert spy determined to find out who killed her lover.
