As a lover of Berlin and its history I was looking forward to seeing this series but what a disappointment it proved to be. Street scenes with cast members dressed in the clothes of the 1920s but filmed with modern traffic and graffitied buildings undermined the whole production for me and destroyed any historical credibility. To say it was a deliberate artistic decision is disingenuous and takes the viewer for a fool - I suspect it was either a case of insufficient funding or just not being prepared to make the effort. I switched off after half-an-hour. If you value any shred of authenticity in an historical drama avoid this shoddy production at all costs.
