Christopher Bahn of The A.V. Club described Liz as a "missed opportunity" because she had such a short time as an assistant and it seemed to him that "the producers didn't really know what to do with a strong, smart female character". Bahn also commented that Liz's "cynicism and skepticism was a good quality for a scientist, but also a sometimes offputting character tic". In an analysis of Doctor Who and the Silurians for Doctor Who: The Television Companion, David J. Howe and Stephen James Walker were positive towards Liz, who they said was "very good foil, far removed from the naïve young companions of the past".
