Man is naturally greedy and precisely due to that greediness, less able to handle the gravity of knowing or seeing a glimpse of the future. But the other issue appears to that man is assumed to be inherently a prisoner of his own knowledge. Determinism is assumed to flow from the vicious circularity of man's knowledge (right or wrongly) shaping human choices which in turn self-fulfils the prophecy. As far as man and future knowledge are concerned, it appears ignorance is not only bliss, it is safer, according to this movie.
Naturally, for future "movie corner" musings, we shall say a lot more than stated in this introductory piece!
