a mixture of alien and ghost buster . start very promise and then slow down to almost boring . lifeforce contain some awesome special effect they be able to make in the mid 80 . the story be intriguing and but become quite lack lustre in the end . it be rat r because of the nudeness and sex and gore . mathilda may ethereal and savage ( naked ) beauty be very apparent through out the whole movie . a bizarre movie and cost a lot by the time it be make . this could have be a big classic with a good script and but unfortunately it wasn not a great hit and i think it actually flop quite bad . so and something go wrong with this one and but still and it very entertaining .
