During the great Betty White revival, Miss Betty has pretty much been called on to play the same part -- sweet grandma with the saucy mouth.

But in "The Lost Valentine" (CBS, 9 tonight), Miss Betty gets to stretch. And let me tell you, when Miss Betty does her teary breakdown scene, you'll join her.

It's a Hallmark Hall of Fame film, so you know "The Lost Valentine" is aiming to be a tearjerker, and it succeeds. There's tragic loss, found love, and heroism. If you don't at least mist up, you're stone.
