At this time of remembrance, it was a useful history lesson, and if we don’t learn from history, we’re doomed to repeat it.
New spy thriller Berlin Station (More4, Thursdays, 9pm) was a little slow-paced, and borrowed considerably from Homeland, but had a promisingly gritty opening, and Berlin looked incredible.
