this movie have a fairly decent premise one gruesomely feature again and again in science fiction film and most spectacularly in alien and some decent he man performances from the male cast . the possessed astronaut wife and to me and be the weak link in the ensemble she doesn not seem to know what to do with her face in a lot of her most prominent scene and for which i blame director corman . give a decent budget for prop and special effect and a more focused and coherent screen play and blood beast might have be pretty decent . but the inherent cheapness of the production design and the continuity error and gaffes undermine the proceeding . for instance and every time i saw the comatose astronaut lay out on an examination table the width of an iron board and i break into giggle and probably not the the emotion the crew want to invoke . and the monster costume need some serious work while fern covered parrot just aren not scary or convincing . still and the premise be strong enough that i hung on to the end just to see how the plot would resolve itself and and the alien motif be sufficiently ambiguous at first that i could sort of think of it a an enigma . and the scene with the shot of the murdered scientist have a bit of punch to it and along with the plot development where the alien claim to have assimilate some of the dead man personality . it corman . it cheap and fast and and mildly watchable if you do not think too hard or expect too much . what more need to be say .
