Yen's comment about the ending of A.I. got me thinking about unnecessary endings to great, or nearly great, movies. Both The Last Samurai and Mystic River run, in my opinion, about five minutes too long (although a decent argument can be made for the ending of the latter). Identity, like many thrillers, had one twist too many. The all time winner, however, would have to be Psycho, which ends with a five-minute explanatory speech so ill-advised that it makes the conclusion of Vanilla Sky feel like a model of restraint.
