Totally agree - but here's the rub: The cartoon crap actually does sell.
Disney has managed to tap into the same market that loves to buy those horrible Disney sequels. The theme parks have become nothing but places to take the kids - it's not about entertaining the whole family anymore, it's about making sure little "Susy" gets to shake hands with Minnie, and "Timmy" gets to meet Buzz Lightyear. So, Disney doesn't have to bother making original experiences or using their product to educate and enlighten - all they have to do is slap some cartoon characters on a ride and call it a day. The masses will eat it up.
It just saddens people like us who enjoyed Disney for something else. Even as a kid, I really didn't care all that much about Mickey. It was attractions like Pirates, Horizons and Imagination that were exciting - and it was what I kept coming back for, even as an adult. Sadly, that era seems to be fading away, and we are being left with something no where near as good.
But hey, if it keeps the kids happy...
