Miley's father, Billy Ray Cyrus, knows a thing or two about overnight success. His 1992 smash single, "Achy Breaky Heart," created a culture of line-dancing men in mullets. Now, a decade and a half later, Miley's own megahit has garnered enough buzz to spawn a soundtrack and her own recording contract. Given the way Disney ingeniously markets its tween idols, Miley could become even bigger than dear old Dad—sans the signature hairdo, of course.

Miley plays a bubbly middle-schooler trying to live an ordinary life. That's easier said than done since her secret alter-ego is Hannah Montana, a world-renowned pop star à la Kelly Clarkson. With only her family and closest friends aware of her complicated double life, things get a little hairy. Characters get themselves into trouble by lying, meddling and (occasionally) disobeying authority. And as usual, adults play the dim-witted fools in this kid-dominated world.

However, amidst groan-inducing jokes, campy slapstick comedy and laughable overacting (particularly from Billy Ray, who plays Miley's onscreen dad), Hannah Montana offers plenty of positive morals. Loyalty, honesty and kindness get preached consistently. Weekly mishaps lead to confessions, apologies and lessons learned. Also, family and friends come first, even when it could be perceived as "uncool." There's been nary a mention of sex or drugs and no innuendo or double entendres. Even a sight gag involving plumbers' pants sliding down showed no more than boxers pulled up high. And while episodes may feature tween girls getting their fashion fix from the likes of Style and Vogue, the show's producers have been adamant about keeping characters' clothing chic and modest.
