"Cushing's coldly articulate and seemingly alien Baron Frankenstein is matched perfectly with the film's minimalist (for Hammer) set design, depicting as it does an England struggling under the environmental weight of lunatic asylums and abandoned estates. This sense of a crumbling landscape is perversely reflected in Frankenstein's drive to experiment and lacerate bodies in the name of a modernist religion of progress. Adding to the film's appeal is a compellingly exhausted and desperate performance by Freddie Jones as Frankenstein's all too human monster. There is a swift yet sophisticated precision to Frankenstein Must Be Destroyed, a concentrated ferocity and subtle unification of narrative, image and theme that is indicative of the very height of Cushing and Fisher's working relationship." - Joshua Vasquez, Slant Magazine
