I have a huge respect for Phil Ford’s willingness to explore adult themes in this story, especially Maria’s experience of her dysfunctional mother. There’s a real humanity to the performances from Maria and her dad that folds in nicely to the alien threat of the week. There’s a Jonathan Creek vibe to this one, especially in the old people’s home with the wily old woman who could unlock the entire mystery if it wasn’t for her alzheimer's - I’m glad her illness isn’t cured by the amulet, an important lesson for the kids. Ford shows us how to write in a way which treats the young audience with respect.
