Nightmare City has received largely negative reviews.
Contemporary Lluís Bonet Mojica of
Barcelona daily
La Vanguardia found the picture to be "another illustration of Lenzi's mimetism, which combines a decent enough plot with the gory spectacle of modern
cannibal cinema. His film even includes a fleeting but interesting representation of nuclear vampirism, a twist on the classic vampire. Sadly, what we have here is still a thinly veiled copy of
Night of the Living Dead." He nonetheless added that "Lenzi manages to keep the viewer's attention" while "allowing himself a few digressions on freedom of the press, urban jungles and ecological suicide", and enjoyed the final twist which elevated it to an "adequate product". In ''
L'Unità of Rome, Michele Anselmi noted that Nightmare City'' "bears the signature of Umberto Lenzi, a prolific workman of facile carnage. [...] Unsurprisingly, the 'message' is tossed aside almost right away, clouded by the 'sick' atmosphere of contamination. Looking to previous films of the genre, Lenzi stomps with both feet on suspense and jumps right to the point, that is the classic explosion of horror and violence. The fantasy, however, leaves to be desired. But maybe it is as it should be: nightmares [
incubi] are serious things, and rivers of blood are not enough to convert them into emotions." New York-based critic Lor. of
Variety found the film "[r]outine and highly derivative" with monsters "noted for their cheap, black-tar-on-face-makeup." He granted that "[s]ince Lenzi is a seasoned pro [...],
City is better made than most films of this type, but lacks the humorous gaffes that make grade-Z junk watchable."
Retrospective Sight and Sound referred to the film as a "spirited, if preposterous, zombie saga" with a "deeply contrived ending". John Kenneth Muir, in his review of 1980s horror cinema, referred to
Nightmare City as a "cobbled together disaster". Muir went on to say it's not the worst zombie film of the 1980s which he felt belonged to
Hell of the Living Dead. In his book
Zombie Movies: The Ultimate Guide, Glenn Kay opined that the film is "way too silly to be taken seriously for even the briefest moments" and that it is "not a good movie, but it is a ridiculously good guilty pleasure with some genuine surprises". Buzz McClain of
AllMovie deemed that at first "[f]ans of psychotronic gorefests will rejoice", before "the plot grows wearisome". He added that "[w]hile there is tension, the horror elements have become comical and the froth falls flat." He conceded that "[t]he makeup effects are okay [...] and the low-budget production details are not necessarily distracting for a genre movie." Andy Dursin, video columnist for
Film Score Monthly, found it "a surprisingly well-executed, low-budget 1980 thriller that offers an interesting variation on the
Dawn of the Dead/
Resident Evil genre of apocalyptic zombie movies." ==Soundtrack==
