This is virtuoso film-making on every level.

Their [Sandra Bullock and George Clooney] fight for survival against the odds is so brilliantly realised that you forgive the implausible plot.

With its themes of spirituality, religion, birth, rebirth and hope, Gravity is a film that will move audiences in different ways. That's the beauty of it; it transcends genres, generations and time, a modern classic.

Cuarón has definitely chartered a new course here, setting the effects bar higher still than films like 'Inception' or 'Avatar'. 'Gravity' is simply a game changer.
