a lot of people say the end do not make sense and but it do . with the female vampire dead the link to earth be break and the ship take off and have pick up a lot of lifeforce from hundred of thousand of soul . enough to re energize those hexagon cell and create new bat creature . it seem they do not have carnal sex and like vampire of legend . vampire bat from out space may be ludicrous and but kill them with with a shot to qui force center below the heart be consistent . all you can ask for be consistency . the viewer have to suspend disbelief and even for scifi . the only problem be have to be a sword or stake and not bullet . that put in a supernatural twist that do not fit with sci fi . so that be a problem . the only major inconsistency i find be kill the male vampire with the sword and but the soul of the girl and carlsen go up to the ship . i assume the male soul also go up the ship and but not show . what about all the human kill . do their qui force ( soul ) go up to the ship a discrete entity and be do all the lifeforce get merge into one and for use a ship see fit . in other word and all the human soul that go to the ship could be re incarnate a bat creature . the basic concept be no more ridiculous than star war force or even re incarnation . this movie be over the top and kitchen sink ( dawn of the dead meet alien meet dracula ) and but in many way profound . it be also a beautiful love story . the beginning and end be ethereal . it both begin ( what be happen to me ) and end a a love story . most of the criticism of the movie be about it be bizarre . so what . bizarre be an art form . as far a be ludicrous and it all fit . the plague concept be much more interesting and subtle than the alien just kill people . maybe they do not need patrick steward blood to form an image of the girl and but it be a very far out and surreal and scene . another reason the movie be hat be because of the end . but the end fit perfectly with the beginning . people be so wrap up in the nude girl that they miss the movie core . it a lover story and from start to finish . it start with carlsen and the girl on the alien spaceship and finish same way . so it fit perfectly . most people be fixate on the hero kill the monster and and this movie do not end that way and which be precisely why i love it . instead and it have a happy end and with the 2 of them go back to ship and to be reborn . way cooler than the hero kill monster end and but that be exactly why it bomb . it be not a straight up horror or even scifi or horror at all and but a love story and with a beautiful beginning and end . all those soul twinkle on the ship . and the crystal room pulsate with new life . most people can not deal with a love story that be also alien meet dawn of the dead meet dracula .
