Paul Cornell,
Martin Day, and
Keith Topping wrote of the serial in
The Discontinuity Guide (1995), "A masterpiece, designed to do nothing more than scare kids, which it does very efficiently. It's a very good Leela story, too." In
The Television Companion (1998),
David J. Howe and Stephen James Walker were also positive, describing it as "a tightly constructed drama that succeeds because of, rather than in spite of, its confined setting and limited cast". They praised the sets, atmosphere, and most of the acting. In
Doctor Who: The Complete Guide, Mark Campbell awarded it ten out of ten, considering it "strong on atmosphere" and "a tense, scary tale that makes a virtue of its small cast and claustrophobic locale." He concluded that it was "superlative in every way". In 2010, Mark Braxton of
Radio Times awarded it four stars out of five, calling the serial "classy, cosy, autumnal
Who", with many positives, including the good characterisation of Leela, the shock of the Doctor admitting he had done something wrong, and the characterisation of the lighthouse crew.
The A.V. Club's Christopher Bahn was critical of the pacing of the end of the story and the "often unconvincing" special effects, but considered the serial to be, despite some flaws, "a classic base-under-siege chiller". Writing for
The Guardian in 2019,
Toby Hadoke described it as "a claustrophobic masterpiece dripping with mordant humour and suspense". For
Den of Geek, Andrew Blair wrote that Leela's line "you will do as the Doctor says or I will cut out your heart" was his favourite Leela moment, adding that "what makes this scene even funnier is that the camera immediately cuts to the Doctor, who bursts into a massive grin."
