...Airport '77 (1977)

Airport '77 doesn't have the sincerity of the original film or the camp value of the first sequel. In fact, the horrible plane catastrophe that is conducive to every Airport film is not even that exciting: the plane remains intact at the bottom of the Bermuda Triangle - big whoop! Brenda Vaccaro, Jack Lemmon, George Kennedy (3x the charm?), and especially Lee Grant are game but someone put the board away - and left the bored in.
