Pretty much all the '90s Disney movies I grew up with as a kid:
Aladdin
The Nightmare Before Christmas
The Lion King
Hercules
Mulan
Toy Story
A Bug's Life
I also greatly enjoyed Mary Poppins, Bedknobs and Broomsticks, All Dogs Go To Heaven, the first two American Tail movies, The Sword in the Stone and Robin Hood as a kid. At least one of them was on TV practically every weekend the NFL wasn't on when I was younger, and you could not pull me away from any of them if your life depended on it.
I also have a soft spot in my heart for The Land Before Time, which was apparently the first movie I ever saw.
Oh, you can add Beetlejuice to the list if you count it as a "kids movie".
