Thundarr is a classic cartoon now (scary, huh?) and I think shows the changes in our culture. Thundarr isn't too politically correct to have a sword-carrying strongman alongside a beautiful princess and a fuzzy side-kick. There's lots of action, but it's mostly the stereotypical good-vs-evil battle, where good always triumphs. This is a good show for boys (because of the action) and also for girls (because the Princess, while perhaps a bit under-dressed, is intelligent and strong). And if you have some small furry creatures running around your house, perhaps they could identify with Ogla (sic?) and his interesting reptilian(?) mount. Thundarr is a bit dense sometimes and you might get a little tired of hearing "Orbs of Light!" but it's a lot better than some of the smucky, politically correct stuff kids watch today.
Think about it like this. Its a show about men and beast who come together to fight the evil wizard Vandar. This might be okay for children, but war veterans will shurely be terrifed by the scenes of violence, as it will remind them of their own times in war.
