Can Sandra Bullock win a second Oscar to go with the trophy she took home for 2009's The Blind Side? Damn straight. She's that dazzling as a mission specialist hurtling through space alone in a damaged space shuttle. OK, she does have George Clooney for a bit, but that's another story. Director Alfonso Cuarón (Children of Men) has taken 90 minutes of screen time and packed them with artistry, emotion and shattering suspense.
