Bearing in mind split Germany and Berlin, there are not too many films and series depicting the events just before building the Berlin Wall -- so the benchmark/background excited my interest already. And the events began rolling immediately: killings, lies, cover-ups, disguises and many other things intrinsic to a good thriller... It did not bother me at all that the pursuit for a certain envelop was the backbone of the Series - there were so many other interesting angles and I was unable to surmise the content of that envelope.
Members of the cast were rather unknown to me (apart from Rupert Vansittart and Adrian Lukis in minor roles), but I found them definitely above average, and it was also to my liking that the performers of different nationalities/ethnicities were used for corresponding performances (although the Russian language had a rather heavy accent, apparently spoken by emigrant actors).
PS I am really surprised that many viewers here have rated this Series so low. I can only suggest them to watch different ones on similar topics, particularly from U. S. and Canada, and then you may want to revise your rating :)
