lifeforce be one of cannon film big flop . it receive mostly bad review and do nothing to help director tobe hooper career in the wake of the spielberg or poltergeist controversy . all of this be unfortunate and because lifeforce be actually a really great movie . it be supremely entertaining and move along at a fast pace and feature some of the most outrageously over the top direction and production and performance and special effect ever to explode across the screen . it must have look bizarre on paper represent the producer of the delta force and the screenwriter of alien and the director of the texas chainsaw massacre and the composer of breakfast at tiffany and the special effect wizard of star war . audience be not ready for this demented exercise in weirdness . what more do you want . we get an alien spaceship full of giant bat . we get a sexy and naked space vampiress suck out people soul . we get explode body . we get zombie . we get possession . we get an s and m interrogation . we get the entire city of london on fire . it dracula meet night of the living dead meet quartermass and the pit meet earthquake . it quite possibly the single most outrageous horror or sci fi or comedy or action or disaster or erotic or apocalyptic epic ever unleash and that be and if there be any other one out there . try watch this movie while chemically alter . perhaps then you will understand . a genuinely feed up experience and and one of director tobe hooper most underrated movie . maybe one day and it will find it audience .
