I've seen this kind of movie before, but there was a focus, an intensity in this one that made me watch it all the way through. You do get some dreadful gaping holes in some TV movies (and I usually switch off when I just can't stand the illogic any more) but this was OK; good acting from the main character (the mute illiterate), plausible emotions from the main carer who is putting her job on the line, and from the support cast, including the abusive parents. An hour and a half you'd be challenged to assemble a decent sandwich in.
