As a Dutchman I found it unbelievable at first that no Dutch was spoken and that all texts on walls, signs, etc. Are in English and not in Dutch. I can't say I got used to it, but gradually I started to appreciate how the series was put together. The setting is well put together and the actors are well cast. The series takes you from the 1930s to the Second World War. And I can well imagine that someone who is not Dutch will be less bothered by the English speaking actors. But for me it feels like I'm watching a series that doesn't take place in the Netherlands. Nevertheless, I give this series a 7.
