I'm sorry, but for you to say that the story was perfect is laughable.
It's a cliche survival story. The characters (all two of them) didn't need any depth layered onto the plot because all that mattered is if they lived. So they could be shallow characters (very shallow) that go from point A to point B to point C and so on until they survive or die.
On visuals and sound, I agree. But the story? Come on. You're just fooling yourself.
By the way, do you think that flying debris was a living entity? I do. It only attacked once Sandra Bullock was at each station and not before.
And by the way, why couldn't Sandra Bullock simply pull George Clooney back once she grabbed his tether and their momentum stopped? Why, when he unhooked, did he fly back like his momentum never stopped and she snapped back in a similar way? That part took me out of the movie because they set it up with text with facts of space and then totally ruin the illusion through inaccurate physics at a crucial plot point.
