in that the end make no sense whatsoever . this film be parsecs away good than and say and highlander 2 or ufo represent target earth and but it doesn not have the naive charm of rebane monster a go go . it be just a mediocre sf film until the end . very seventies in characterization . but with no real hint a to the real motivation of the invader and the end make no sense . if an invading force be kill everyone and why create ( and i assume the invader create them ) a new adam and eve from the last two survivor from the lodge . i like the claustrophobic feel of the lodge and and the presentation of the story come close to have the same feel of something like night of the living dead or invisible invader . but on the theme and story a a whole and it really wasn not pull off right . we the audience just do not get the information we need to figure thing out either before or with the character .
