Parents should know that this series is geared toward adolescents. Its main focus is a relationship between a boy and a girl who bond over a shared love of music. Their friendship, which develops from an initial dislike of each other, is a good reminder that relationships with the opposite sex don't have to evolve into romantic intentions. The story itself is a bit far-fetched, thanks to the unlikely absence of adults to monitor the teens' unrestricted movements, and it does prompt thought about the role the Internet plays in assigning fame. On the whole, though, there's no reason to worry about the content, which often calls on silly sight gags and quirky characters for its laugh-a-minute comedy style.
