Personally I miss old Disney movies, like... Lion King, Beauty and the Beast etc
The Disney channel today doesn't even play such animations anymore.
Younger kids these days only know of 3D animation movies from today, Hanna Montanna and so on :/
Of course I appreciate the advance in technology regarding animation (otherwise we wouldn't have watched Avatar :p), but I still value what I grew up with. It's a pity kids of today wont experience such things.
Even 80/90's (especially the latter) music was a lot better.
Another all time classic is the Sega :D
So what do you miss most?
