I think that the show isn't really a bad show. I find it quite appealing in many ways. However, given the violence, and inducement of fear, it is unfit for say, an 8 yr. old, which is what it is rated for.
The biggest reason I feel this way is because of its scenes of violence. Deaths are not only presumed, but are indeed shown for all they're worth. One episode (I believe it is number 2), shows Modula, the main villain, pick an opposing soldier up by the thorat, breaks his neck, and drops him to the floor. There is also an episode in which people are shown drowning in a river while groaning and crying for help. This kind of material is not age appropriate. The show also operates mostly in dark color contrast and many topics, along with plot, speech, and other aspects are very dark. I think that if the show could just ease up on its level of what one may even call, morbidness, I think that it could be a very entertaining program suitable for all ages.
Also, just to throw one wild bone out there, the main male character, Lance, is cool I gues.... but I think that he is greatly lacking in the 'role model' field.
Well, this is just the opinion of an 18 year old boy, man, or whatever you want to call me. I just felt very strongly about what I saw on a kids network one night that I still know to be the home of classics such as Scooby-Doo. Anyways, just be cautious.
