It's a rare airline disaster film that makes you want to spend more time on the airliner, but then, United Airways Flight 1549, which hit a flock of geese after takeoff on Jan. 15, 2009, and wound up on the Hudson River, was that rarest of airline disasters: one with a happy ending. Sully, starring Tom Hanks as the pilot who guided the fateful flight over its final 208 seconds, is thrilling when we're on and around the plane (seeing that giant CGI bird splash down, especially on an Imax screen, makes you realize how improbable the whole enterprise was) and too often thudding when we're not. Director Clint Eastwood gins up the drama of the National Transportation Safety Board's postaccident investigation, setting the stage for a creaky Platonic dialogue about the value of operating on intuition and experience rather than relying on the data-crunchers that know nothing about real life.
