If you don't know by now, this science fiction adventure is one of the original "mind benders", an outer space flick in which aliens use mind control.
And against this kind of mind control, what can one do? If a character is powerful enough to warp your sense of Reality, then how can you truly fight it? We get a full throttle effect by showing a full length movie in which the outcome is really decided immediately, only no one knows it.
The super formidable enemy, the one you must rely solely on God's graces, or luck, to beat, is the one who controls all you perceive and conceive, the one whose control over what you see, hear, sense, is completely contrived by this foe.
We go through a series of adventures, and the characters seem totally out of control, but that's because they have no idea what Reality is any more. They go through total Chaos.
And the ending, which I won't spoil, leaves the audience in total Chaos, but also explains that indeed, there is nothing to be done but rely on luck if your perceptions are out of your control.
Overlooked film. It actually is better than many of the later ripoff versions which tried to be too contrived in modernism, by that I mean that the later films wanted to establish that SOME humans were superior enough to overcome this obstacle, which is flat out silly. If you have no direction and no vector, you are totally helpless to change your situation. This film goes under the old school of Credibility premise instead of the 1970s contrived "Man is God" premise.
