Doctor Who: Lurkers at Sunlight’s Edge by Marty Ross (Big Finish, 2010) Although H. P. Lovecraft wouldn’t have been out of place in Doctor Who’s much-vaunted gothic horror run, Lurkers brings precious little originality to the homage. Ace has some nice moments but the guest characters are tired-and-true stereotypes and the plot unbearably cliched.
Dr. Seventh by Adam Hargreaves (BBC, 2017) Though drawing a pretty faithful Seventh Doctor (and Ace), Hargreaves manages the almost inconceivable feat of making his Cheetah People less threatening than those of the original serial. In mitigation, the Master’s cameo is era-appropriate in its preening reveal and blustering fizzle.
Doctor Who: The Dark Husband by David Quantick (Big Finish, 2008) Whereas humour in Doctor Who has always worked best in moderation, Quantick can’t seem to help himself: the jokes never relent, meaning that the Doctor, Ace and Hex are constantly, frivolously undercutting the drama. Thus a potentially intriguing SF tale is stillborn.
