Gravity. Stunning visuals. Forget everything you know about low earth orbit (LEO). But, but, but, why is Hubble so close to the space station? Don't think about it!  I think this one calls for IMAX, but I think the only IMAX release is 3D. It was a bit distracting when space debris comes flying out of the screen, but there was a minimum of that stuff. I really want to know how they shot the micro-gravity stuff. Sandra Bullock takes very good care of herself.
