In science fiction circles, there’s a style of story telling called “hard science fiction,” which attempts to portray the future as realistically as possible, making reasonable extrapolations from known facts about the Way Things Work. Gravity is about the hardest hard science fiction movie I’ve ever seen. It feels like it could happen tomorrow.
It’s scary as hell and makes you realize just how laughable most science fiction is these days with their artificial gravity, and force fields and ray guns. Sandra Bullock and George Clooney sell their respective roles convincingly, but the real stars are the effects people and, no doubt, gazillions of people who worked endless hours to get all the teeny tiny details just right.
Gravity also makes you appreciate just how fragile human beings are and just how quickly things can go Terribly Wrong. To say any more about the plot would spoil it so I won’t. But I will say that I’ve seen it both in 3D IMAX and regular screen. You still get the a good sense of scale on the regular scale. But dang, the 3D version makes the devastation all that more scary. Highly recommended to see it in 3D.
