The New York Times has a negative review from the time of the film's release. Slant Magazine gives it 4 out of 5 stars and opens with this: "Underneath its sci-fi horror trappings, Lifeforce is a romantic comedy with a splash of gothic longing for flavor."

Roger Ebert says,

"Lifeforce" survives and, as far as I am concerned, it plays much better today than most genre films of its time, not to mention those being produced today. It may be tasteless and lurid and demented beyond belief but, I for one, would take its glorious excesses over the turgid ones offered up by Peter Jackson''s apparently-never-ending take on "The Hobbit" in a heartbeat. Now that enough time has passed since its initial failure, perhaps it will now finally be able to attract the audience that it has always deserved.

HorrorNews.net opens by saying, "If you’ve never seen this movie it’s the one with the nude space vampires." Rotten Tomatoes has a critics rating of 67%.
