Within the first instants, one is sucked in by the immensity of space. The immersion is total, thanks to the 3D which undeniably brings something extra in certain scenes though this technology is still quite perfectible, and the soundtrack which is in complete harmony with the action, though sometimes more silence would have been appreciated.

Therefore, if you consider the movie as an "experience" (as it should be), it's great, especially at the beginning when it's totally captivating, because for the rest, it is a classic survival movie with very conventional developments that sometimes even relies on some cringe-worthy, typical Hollywood style melodramatic clichés.

All in all, Gravity is a unique experience, a great slap to the face, but it hardly qualifies for the masterpiece rank a lot of people are crediting it.
