Obama says the primary season is like "a good movie that lasted about a half an hour too long."

Is politics all about entertaining us and managing our moods and attention span? Does Obama more than Hillary Clinton think that it is? Or is he giving us something like the Janet Leigh perspective on "Psycho"? It was really great when I was doing so well, but then...

(I know there must be a more apt movie analogy. Can you think of something where an actor has a great role or plays the role very well, but is overshadowed or not up to the part in the last half hour?)

ADDED: You know if this campaign were a movie, Hillary would have to win... or at least "go the distance." She would be the central character, because the story is most interesting from her point of view. She's got a fabulous backstory, which includes suffering, but she starts out on top and full of hubris. Along come the one man who can block her path to fulfillment. She's torn down and laid low, humiliated once again. But she needs to learn to fight, and she's not going to give in. Come on, I'm getting chills just sketching it out. If the movie was about Obama, sure, it should have ended on Super Tuesday, with just an epilogue showing him in the White House. But if he's not the central character, we're still building toward the most thrilling climactic scenes.
