I can honestly say this is by far the worst thing I've ever heard from Big Finish, a company who's quality is usually very high. There is terrible direction and writing throughout, the actors are decent but they are not given anything to work with. There is not a single relatable character; Jenny is written as a generic goodie with plenty of pep and zero personality. Even the theme tune is terrible.

Matt Fitton wrote the brilliant Technophobia which kicked off Tennant's run at BF, so I know he can come up with something more intriguing than this. Then again he had some ready made characters to run with there, here he had the task of establishing who Jenny is outside of the context of her birth episode. Having heard the first hour of the Jenny box set I am left none the wiser.
