The movie does nothing to get it's audience to get to know the characters, even Sandra Bullock's character. None of the characters were ever introduced, If you do not know who the actors were, Conley and Bullock, you would not feel attached to them at all. The visual effects were good and there was a semi-solid use of physics concepts, but it missed out on so much. The sun is not yellow, we see it as yellow because of the atmosphere, which in space is nonexistent. The movie should have had an introduction to it. If you watch this film on the big theater with 3D glasses, you might like it, but as soon as you buy it to own, it will loose 70% of it's value as the movie is mostly a visual spectacle no plot or story to be praised for.
