Gravity. A masterpiece. An ode to the world, to life.
The protagonist (S.Bullock) has nothing to lose, her daughter died in an accident so she went to the space.
There, she strives for her survival during the whole film and demonstrates herself the value that life has and how beautiful the world is, even if it's not perfect.
A movie with a title that explains everything. At the end of the day what the person just needs is gravity to stand up on the earth and live.
A part from that, the movie becomes a masterpiece because it's pure cinema. The photography and everything conjured to end up with a film that has been qualified as a 'classic' of cience-fiction.
Sandra Bullock's perfomance was amazing, probably the best of her careerMust see in 3D, you enter to the word that the director, A. Cuarón, made for us.
