This film is an excellent example of what can happen when all of the effort of special effects is replaced with maximum effort into the script.
Definitely a thinking man's science fiction film whose intellect sacrifice none of the science nor none of the fiction.
The plot utilizes the fantasy element of the genre to delve intricately into themes of the pysche such as regret, love, pity, self-inflection & even the most monumental of these concepts, the justification of life and death. It does so with enough room to allow the viewer with no other answer other than the store of reflection which he or she carries into film, before & after.
Despite an incrimately moving pace that many of today movie-watchers may at first be uncomfortable with, once you settle into it's richly layered rythym, Solaris is a great film whose provocation of thought is as richly satisfying as is the grandest world-demolishing visuals of any other more explosive sci-fi films.
