I found the premise to be of interest, but I also found the storyline lacking in focus and the dialogue absent of any subtlety. Although the boy is the first Elspeth Eric character that I have developed any empathy for, I was consistently distracted by the actresses voice (IMHO it didn't even remotely sound like a 10 year old boy). There were no real winners or losers in this episode - maybe that's Eric's point - but stories without hope are better written by the Cure.
I will give the author credit for tackling a story full of hard issues (child abuse, adoption, etc.), but I thought the episode fell far short of the usual script quality.
I gave this episode a "2" - I dunno, maybe I'm being a bit too hard.
