Having read the book before I saw this I though it was a huge disappointment. They completely missed the point of the story, which was philosophical rather than emotional. Basically, the movie took an awe-inspiring "what if" thought experiment - of finding a very advanced non-human intelligence (which, surprise surprise, doesn't have two arms, two legs, a body and a head) and the problems of trying to communicate with such a radically different being, especially when it doesn't seem interested in communication, and how we can relate to it with our own limited human experience, and squeezed out all the juicy intellectual bits. Solaris was supposed to be the real star of the story and the screenplay instead turned it into background wallpaper. All that was left then, was a sappy love story set in space. It is frustrating to think about the potential that was wasted. Mr. Soderbergh could have made a classic sci-fi film here, if only he'd made an honest attempt.

The funny thing is, if I hadn't read the book I would have liked the film, because it is well directed and has a nice atmospheric mood. There's nothing inherently wrong with love stories either. Just.. call it something other than Solaris, give the characters different names, don't do anything to remind me of the original story and I'd say it is a good movie. But as it is, it's an extreme disappointment.
