Great musical score, CGI and acting--particularly Clooney

Rating: 9/10 (21 October 2013)

Is George Clooney the most underrated actor out there?
While this is obviously Sandra Bullock's movie (and she's great in the role), I'm not so sure you would have cared as much, had Clooney (and his character) not been present. His calm and selfless demeanor was the counterpoint to Bullock's natural overwhelming fear when things began to go bad. I can't think of another actor in that age range who could have pulled off Matt Kowalski's role--maybe Brad Pitt on a good day?
Just a nit: Bullock's character referred to Matt Kowalski as "Lieutenant" twice. I have to believe an officer of Kowalski's age and experience (shuttles since 1995) would be higher up the food chain (minimum Commander, most likely (Navy) Captain.
