A series of clever episodes with extremely good acting and subtle situational humor. I liken it to Mission Impossible except you must travel thru time to pull off the caper. That adds the novel ability to take any historical incident , major or minor, and expand your historical appreciation of the event. And the movement back and forth thru time demands your attention to the story, because your disbelief is always just below the surface, crying to be listened to. And it does improve your Spanish.
