My niece developed an interest after watching the Fantasia disc I bought for her 6th birthday. Simple exposure is usually enough; the music itself does the rest.
Now we have these “message” type cartoons and they suck. It used to be Cartoon Network would run the old Warner Bros, cartoons, but then they started butchering them for PC considerations such “violence”, “stereotyping”, and other liberal nonsense.
One of the things that drove the libs nuts was the characters were always getting shot or blown up or falling off cliffs and such. These morons actually believed kids could not understand the difference between cartoon fantasy characters and acting out in real life. Good grief! How stupid is this? At 8 years old I knew cartoon characters weren't REAL.
