Improbably entertaining Gravity celebrates the pursuit of life as not only primal but the only ethical course of action

Gravity is an entertaining space thriller that is the new 'must-see' film. A brief, pulsating exploration of claustrophobia of open space. It is fast-paced, poignant, scary and even funny. It celebrates the pursuit of life as not only the most primal but the most ethical course of action. It is one of the best single-idea movies out there.

Sandra Bullock, the much-maligned, unassuming super-star, makes a giant comeback with a strong, believable and rare likable performance. She makes you want to root for her no matter how improbable her pursuit seems.

Alfonso Cuarón, the young Mexican director, adds another excellent film to his small but wide portfolio.
