Watched first three episodes last night, enjoyed them immensely. The cutting between real and cgi was a bit jarring at first, but once u get over that little flaw it's a really good watch. Also, after living there for 4 years it was nice to hear the language again. (And see how much I still understood)
Was also good to see a bit more subdued version of the Russian WW2 effort for a change, instead of the usual desperation/propaganda/walking-mine-clearers that is more commonly portrayed.
Excellent so far, and incase anyone hasn't seen it, I also highly recommend the big-budget Russian film '9th Battalion' about the Russian-Afghan conflict. Its like the Russian version of Full Metal Jacket. As with this series, you can get it with subtitles on youtube.
