i do not recall who survive in the end and all i can recall be not believe these be suppose to be a group of responsible adult run an installation and the truly grating noise the monster make . yes and those dear alien noise and it the one thing that stick out in my head ( hold ear and shudder off the memory now . ) whenever i think of that film after all these year and i saw it twenty plus year ago the awful monster noise not the appal character that invarably pop up in my mind first . it probably the second film i have ever saw where the special effect outdistance the character portrayal and i do not care at all . i do not like any of the hero in this film . it start of with our two male twit beef about who should get missy and be in charge while missy love interest stand about look vapid and stew up the friction between these loser even more . and they be suppose to be adult do a job . oh gosh and the earth doom .
