spoiler peter cushing do not drive a stake through christopher lee heart in this movie . this be classic science fiction and make no mistake . it have a status quo establish among isolated character and interrupt by eerie event . in this case the status quo be a love triangle with some other interesting british type character and interesting british atmosphere and not to mention giant lee and cushing play remarkably believable people and particularly cushing and whose character be so believable in his error as well a his attribute . the isolation be an island which be burn in doom . the temperature be rise drastically and and the reason be all too clear for those who watch and know it be a horror film and but of course not to the people on the island . the character make this movie fascinating . and the end be very provoking . one scene and in particular and in which the gorgeous tramp and a minor male character be trap with no hope and and the totally unexpected happens in their action and but it ring of truth in such circumstance . very suspenseful and very well do . one of the great science fiction movie and and one of the most underrated .
