Ferber’s First Law of Aeronautical Entertainment: The good movie is always on the flight going the other way.
Corollary (”Round-Trip Switcheroo”): By the time of your return trip, they’ve changed the movies.
(Ferber’s Trump of 2008: “I have a video iPod, suckers, and no, I will not be needing your crappy $2 headsets.” Turns out a nice weepy Doctor Who episode can hold it’s own against “Bee Movie” any day.)
