I just watched all 3 episodes in a row.
It is a good dramapiece.
I really liked that it is in german,creates the right athmosphere.
(Had to use english subtitles, my german is not the best)
I sort of liked that they toned down the combat, attrocities and general gore.
It is used to drive the story, and at the same time not leaving out or beautifying what really happend.
Those that want to see that part, the "real" Östfront can see other depictions of it.
The main focus here is the human story,capturing the zeitgeist.
Apart from a few silly plotlines, I enjoyed this miniseries.
