The psychological horror of this, and the way it comments on soldiers being objectified in abstract moral debates over war, is astounding. I didn't 100% catch why we have the Doctor and Charley traveling back in time, or how that works with the ending. But this was a fabulous first outing for Jaine Fenn.
I enjoyed this, I think more for the characterization than anything else. The story was interesting (even if it didn't fully grab me), but I think Jaine Fenn absolutely nailed the voices of both Charley and the Doctor. It would be easy for a newcomer to miss that, so for her to have done so so masterfully is very impressive.
