My tween daughters love both of the HSM movies and I try (unsuccessfully) not to rag on it too much. The first HSM had a munchkin basketball team that was unintentionally funny. None of the players were 6 foot yet they won the state championship. Yahoo for Spud Webb.
The intense interest the kids have for this is intriguing. They buy the CDs and watch the original movie repeatedly. I guess this is like the teen heartthrob mags of decades past, but the heartthrobs move and dance and sing.
