Variety magazine, in their review, called the film "lethargic between its terror scenes, making it a test of patience for all but the most fanatical of horror cheapies." In a similarly negative review,
Time Out magazine called the script "banal" and the actors "uninspired," as well as calling the film "visually as uninteresting as a catfood commercial."
Janet Maslin from
The New York Times wrote, "The movie winds up more gruesome than scary, especially because the 3-D tricks are both repetitive and infrequent. It provides only a few strong shocks, chief among them an
Alien-inspired scene that has the creature bursting forth from the body of one victim. These thrills notwithstanding, this is a badly acted B movie without much flair for involving its audience." J. Doyle Wallis from
DVD Talk gave the film 2/5 stars, stating that the film was "just for the nostalgic 80's horror film fan, and loony Demi Moore/Stan Winston stalkers". Scott Weinberg from
eFilmCritic awarded the film 1 out of 5 stars, calling it "[an] Amazingly BORING sci-fi horror".
TV Guide rated the film an abysmal 0 out of 5 stars, stating that the film was "[a] crushingly inane mess". In 2019, during an appearance on
The Late Late Show with James Corden, Moore named
Parasite as "the worst movie [she had] ever been in". ==See also==
