first and i be a big fan of alien and alien ii in my opinion both of these movie create and define the si fi horror genre a we know it today . i notice lifeforce be often compare to the alien saga after view this movie i would highly disagree . there be some okay special effect with the alien vampire and and the story line might have be acceptable . i just can not get past a naked woman space vampire throughout the whole movie and this be absolutely absurd ( although she do look good ) . add in a bunch of bad british acting and it pretty much over . most of the movie end up take place in london or somewhere in england and so after the first 20 minute you lose the outerspace setting and any hope of some real si fi horror action and suspense .
