While the presence of cameras and White House replica sets bring a touch of theatricality to proceedings, everyone taking part is fully committed to the exercise.

As a simultaneously slick and provocative entertainment, “War Game” is chilling and a tad infuriating, offering a white-knuckle ride that may feel a bit too fresh in the memory for viewers who are still traumatized by the real thing.

This was fascinating, urgent and important.

I left War Game with questions about the exercise’s purpose. I didn’t learn much and I’m not sure anyone in the situation room did either. That said, for capturing the precarity of the US government in such scary circumstances, this is worth your time.
