This movie is philosophy, it is a lesson in morality. It is proof that sometimes knowledge is not achieved by forcing the fortunes of life, but by meditating. It seems it was the inspiration for "Solaris" (1972) (more the movie than the book) and "2001: A Space Odyssey" (1968). However, even if it has the ingredients to be a 10 movie, I have noticed the love factor that it is in shoehorn. I feel like he's forced and overactive. I think it is the only thing that could not be taken from paper to the big screen without losing its splendor.

On the other hand, and to finish, In fact, unlike other science-fiction movies, we must also highlight the aging that this movie has sufferes and some mistakes in lack of imagination: go faster than light, talk about millions of years (it is enough to compare 1900 with 1999 to see that it does not take millions of years to reach the pinnacle of knowledge), space suits, the clumsy motor skills of the robot and its design including its mechanical mechanism (worth the redundancy), preserving religious traditions and more. With the latter I am not talking about mistakes nor do I want to discredit the film. It's just that the 10/10 science fiction movie must be the one that time doesn't pass so overwhelmingly.
