I wouldn't count The Lion King among Disney's "older" movies, but at any rate, I'm not sure if there's been a significant move toward animations that scare kids less. Sure, early years included the nasties of Snow White and Sleeping Beauty, but just look at the villain in the last segment of Fantasia 2000. Besides, who's ever been scared by Cinderella?
Of course, if you really want Children's horror, look no further than
Doctor Who. Scaring kids since 1963 while providing entertainment for adults simultainiously. Apart from during a 16 year period between 1983 and 2005, when it was purely in novel and audio drama, and solely produced with old fans in mind, (and a comic strip in the montly magazine) form, apart from a brief foray into American television-movie territory.
I mean, I swear, I didn't think you could show people being mercilessly ripped to shreds by a werewolf on Saturday night at 7pm on BBC1, but earlier this year, it did. (granted... It was bloodless, which is something else that suprises me. They managed to not unrealisticly portray it on screen and simultainiously not show any blood)
