PBS Masterpiece Theater comes through with another Nicola Walker vehicle, Annika. This one is mostly episodic with some character through-lines. The most charming conceit is letting her break the fourth wall and tell us about Norse sagas, Shakespeare, Greek mythology and parenting.

I have a bit of PTSD every time she turns her head to talk to the camera while driving a car. Unforgotten fans will understand.

We're watching it on the PBS streaming app on an Apple TV.
