The acting within the arias was generally acceptable but not particularly creative. The stage directions for non-singers (except for the child for the most part) and singers when not acting was either not clear, overdone, or static--especially the marching troups (?) or prisoner guards (?). Elevation distinctions could have been used more often.

Lighting was boring.

To make this libretto interesting is certainly a challenge. One possibility you might wish to consider is doing it in modern style with, perhaps, a film background suggesting the complication of thoughts and feelings behind and between the repeated words in each aria as well as the background war details for the men.

One could not ask for better singing. Not even a hair flat thoughout (with only one instantaneous exception) and richly nuanced. This plus saved the night.
