This was the last film that made me actually angry. Specifically, the bit where Sandra Bullock has a toehold on some cables attached to the space station and she's holding onto George Clooney. All she had to do was slowly contract her body and they would both have drifted to the station and been able to grab onto something.
In the film George Clooney is being pulled away from the station by a force that is at right-angles to anything we know. When Sandra lets go, that same mysterious force sends George whistling off into the darkness. Considering the film is called Gravity, you would have thought that somebody would have looked up what that is at some point.
