I saw it with my wife this weekend. Other than no story behind the whole movie, it was a great movie. The effects were awesome and I thought it was the best use of 3D that I have seen yet. It almost made my wife sick with all the hurling through space stuff.
The best part was as we were leaving, we overheard and older lady talking to her husband saying that she never wants to go to space now. Like it was every a real option
