Ah yes but as you said,what a good movie. The destruction of the ISS in 3d was phenomenal on a big screen.
The movie got a bit of criticism from the scientific community because it did try to get many things right.

One additional issue for example is how Bullock managed to open the airlock from space to get into the station. Apparently the hatch would normally open the other way and would be impossible to open without depressurising the interior first.

I think it's nevertheless one of the best sci-fi movies.
