This technically brilliant film contains beautiful shots of the earth viewed from space, there are some tense moments as the two space workers (Clooney and Bullock) struggle to survive when they find themselves stranded after a disaster not of their making and it is intriguing to watch them floating about surrounded by a motley collection of objects and dealing with weightlessness in a matter of fact way, at least until calamity strikes. As with most adventure films, the desire to create ever more exciting situations sends plausibility spinning into the outer galaxies and it is probably an advantage to be ignorant of some of the basic laws of physics. At the end, despite the ludicrous twists, the film succeeds in leaving you with a sobering sense of mortality combined with the strengh of the will to survive.
"Gravity" is definitely greatly enhanced if seen on a large screen in 3D.
