I didn't like it
It was just too slow and boring for me to enjoy. There were moments of intrigue, mostly near the beginning of the movie where the man gives his testimony of what he saw on the surface of Solaris, but it didn't go anywhere. I was hoping to see this giant kid eventually, but nope.
The whole movie was very confusing, and this was exacerbated all the more by how slow it was. Plot details just ended up going over my head because I could barely pay attention throughout. I actually had to stop and consult wikipedia's plot summary just to know what the hell was going on. I definitely couldn't sit through the entire movie in a single sitting.
I wanted to like it, I really did. The movie actually reminded me of 2001 A Space Odyssey, which I also did not like (but liked more than this). I suppose if you loved that movie, you'll love this, but if you hated it, then you'll prolly hate this one as well.
