My favorite of the Animated movie is Little Mermaid.
I'm a huge Alan Menken fan. Disney has an incredible song book. I prefer Disney animated features over any other company's due to the great story telling. I'm to the point where won't go to an animated feature any more unless it's Disney.
"Old school" Animated: Sleeping Beauty
"New school" Animated: Wreck-It-Ralph
Live Action + Animated: Mary Poppins
Live Action: The Happiest Millionaire
Pixar: The Incredibles
Favorite at this time is Tangled, Frozen very close behind. I'm one of the 3 people in the world who didn't see it in theaters and did not get all of the hoopla until last week when I bought the dvd--WOW count me in as a fan.
Toy Story and Lilo and Stitch have special places in my heart because those are from when ds was small.
Beauty and the Beast makes my heart all fluttery and the tears flow freely.
Princess and the Frog--love the music and also brings a tear to my eye-darn firefly
Can't pick just one... But I can narrow it down: Mary Poppins, Tangled, and I gotta admit Frozen!
However, I'm also a huge fan of the original POTC as well!
