i first saw this movie when it originally come out . i be about 9 yr . old and find this movie both highly entertaining and very frightening and unlike any other movie i have see up until that time . basic plot represent an expedition be send out from earth to the fourth planet of altair and a great mainsequence star in constellation aquilae to find out what happen to a colony of settler which land twenty year before and have not be hear from since . theme represent an inferior civilization ( namely ours ) come into contact with the remains of a greatly advanced alien civilization and the krell 200 and 000 year remove . the seed of destruction from one civilization be be pass on to another and unknowingly at first . the theme of this movie be very much good vs. evil . i first saw this movie with my brother when it come out originally . i be just a boy and the tiger scene really do scare me a do the battle scenes with the unseen creature force . i be also amaze at just how real thing look in the movie . what really capture my attention a an adult though be the truth of the movie forbidden knowledge and how relevant this will be when we do ( if ever ) come into contact with an advanced ( alien ) civilization far more developed than we ourselves be presently . advanced technology and responsibility seem go hand in hand . we must do the work for ourselves to acquire the knowledge along with the wisdom of how to use advanced technology . this be and in my opinion and the great moral of the movie . i learn in graduate school that knowledge be power be at best and in fact and not correct . knowledge be potential power depend upon how it be apply ( . if it be apply at all . ) [ it not what you know and but how you use what you know . ] the overall impact of this movie may well be realize sometime in mankind own future . that be knowledge in and of itself be not enough and we must and must have the wisdom that knowledge depend on to truly control our own destiny or we will end up like the krell in the movie just wink out . many thanks to those who respond to earlier version of this article with comment and correction and they be all very much appreciate . i hope you be a entertain by this story as much a i have be over the past 40 plus year . rating represent 10 out 10 star .
