My Nominee for the Best Family Film Ever:
"Akeelah and the Bee." It is sweet without being cloying. It is about real people in real situations. Nobody gets shot, beheaded, assualted, or molested. It is a true classic.
But let me caution you: you will be shedding tears of joy at the ending (which I won't reveal.)
"Don't sweat the small stuff, because it's ALL small stuff." (Jerry Seinfeld)
