There are two kinds of moviegoers: those who stay to watch the credits and those who — never mind; they're already gone.
If, reader, you go to The Simpsons Movie, stay to watch the credits, and you'll be rewarded with a few surprises.
The movie proper has many fine touches, including a well-detailed low-budget motel room (in the Red Rash Inn), a Disney spoof, and a swipe at Fox Broadcasting. My favorite touch: the split-second that evokes the famed George Tames photograph of JFK leaning over a desk in the Oval Office.
