Winx Club (Nickelodeon)

Bloom (voiced by Liza Jacqueline) is an ordinary teen whose life changes forever when she rescues Stella (Amy Birnbaum) from a pack of monsters. Once the dust settles, Bloom is shocked to learn that Stella is actually a fairy princess from another planet -- but that's nothing compared to Bloom's reaction to discovering her own magical powers. At Stella's urging, Bloom enrolls in Alfea College, a school for fairies in the Magical Dimension. Together with their roommates Musa (Lisa Ortiz), Tecna (Cathy Weseluck), and Flora (Kerry Williams), these powerful fairies form the Winx Club and set out to counter their enemies, a trio of witches from a rival school. They're often joined by four magical Specialists, and later episodes show them joined by new fairies Layla (Christina Rodriguez) and Roxy.

Start with mystical fairy powers, add the ability to fly, flashy clothes, and the constant slumber-party atmosphere of the fairy boarding school, and you have any tween girl's recipe for fun. WINX CLUB is teeming with witches, warriors, and magical mysteries, but it's also bogged down by some content that's not so great for its very impressionable target audience. The girls sport tiny skirts and tummy-bearing tops that show off their impossibly small waistlines and slender legs, and everything from their long, flowing hair (pretty, but not very practical when you're fending off bad guys) to the mere poses they strike invokes some sexual undertones. And all that's in the absence of the guys, with whom they share hefty doses of flirting and eventually some dates and kisses.

Violence is the other sticking point, although this is probably less upsetting to parents than the sexiness since it's pretty fantasized (mostly energy balls and magical powers), and blood is minimal. On the upside, though, if your tweens do tune in, they'll be treated to an imaginative story with bold, take-charge heroines who find strength in cooperation, creativity, and a thoughtful approach to solving problems.
