I've been watching very good Russian series on TubiTV, but "Mata Hari" was so disappointing. I've just watched Episode 1, and it was enough. The series is badly written and the acting is so poor. It follows "by the book" all the politically correct clichés of today's productions, where every man is wicked and violent and she, as a woman, is always a victim of circumstances. Deep as a paper foil. Good for Netflix "modern audiences", but not for anyone who is looking for an interesting story about this controversial character. Mata Hari deserved much more.
I gave the series 3 stars only for the production design, nothing else. If you are looking for good Russian series, try "The Golden Horde", "Spies" and the light-hearted "Anna Detective".
