Saw it tonight in Regal RPX 3D.
Some nits about orbital mechanics aside (it would not be as easy to hop from shuttle to station to station as in this film - they fly in different orbital inclination, altitudes and velocities and aren't that conveniently close to each other), I thought Bullock and Clooney did a fantastic job, the effects were simply incredible. It was hard watching all of that beautiful space hardware (billions of dollars worth) get destroyed, though.
(I would have been more impressed if the Chinese station had been harder to get to - say, she had to do a burn in the Soyuz to match orbits, and drift for a while until it caught up, only then to run out of fuel and need to use the landing rockets to get there - would have been more realistic and not required much adjustment to the story)
