Assuming you're watching the first 2 episodes - the series is wonderful. Later on the details become more and more far fetched, less and less reasonable, twisting the plot for the sake of the script, to depict semi-legitimate events. On the later episodes, seems as if it's been worked on by a tired screen play writer that only wanted to finish the plot and tie all ends together - at all cost.
The story is revolving around life of few characters, forcely binding them together. while reflecting the IDF as a disoriented military, and reflecting lack of solidarity within its lines. Aside from archive footage that helps for the authenticity of the series, during the episodes - any relation to the war is not reflected. Looks like a scripted set and not time of a real war.
In summart- started great and authentic, (more or less till ep 4) rest of the episodes are disappointing.
