Great to watch.

Good acting, good shots, good colour grading, good atmosphere. Nice building up tension and also explaining something to a greater public by making it visual and exciting.

Only one thing kept me back for giving it the full 10 points, the language. It would be absolutely perfect in every sense if the actors all spoke Russian during the entire series. Language is an important aspect, also accents, to fully raise the atmosphere to the full 100 percent.

If the language, or accent, does not bother you at all, I must say it is nice to watch it without subtitles, than you will like this 10 out of 10 stars.

Recommended: Yes.
