Rating: 9/10 (18 December 2013)

This is a great film for teenage boys because it really gets to grips with what it is like to be in space. And as Sandra Bullock has to carry most of the film, it may suit teenage girls too. But many reviewers on this site seem to have forgotten the simple physics they learned at school. Yes, objects are weightless in space. But objects still have mass. And mass times velocity is momentum. That is why Matt has to detach himself. His momentum is too high. Weightless yes, but too much momentum. Notice that whenever anyone opens an airlock, the pressure of the residual air in the airlock means it bursts open and you have to cling to the handle.
