Few shows bottle pure delight like Glee, a Fox TV series about the ups and downs of a high school glee club, or show choir. The show lures you in with its musical numbers, a mix of classic rock and Broadway show tunes performed by a cast of marvelous singers and dancers - but what keeps you watching are the wonderful characters. Glee fuses adolescent soap opera, the comic pettiness of academic politics, and exuberant song and dance. Somehow, the characters manage to be cartoonish yet multidimensional; even the nicest characters are capable of being jerks and the most manipulative have moments of sympathy or grace. Throw in vividly colored costume designs and blisteringly funny rants from ruthless cheerleading coach Sue Sylvester, and it's easy to see why Glee became an unexpected hit.
