Starting with the best...
Pixar: Has yet to let me down
Early Dreamworks: traditionally animated (only 5 of them)
Early Disney: traditionally animated
Later Dreamworks: everything past Kung Fu Panda
Disney definitely I am the biggest Disney nerd in the world. I love a lot of Disney movies. My fav would be Tangled,Enchanted,The Little Mermaid, Beauty & the Beast etc.What I like about Disney movies is hat each one is all about dreams coming true whether you’re a girl from another world, a non human(mermaid, fairy),seeing the world for the first time and acceptance. The ONLY non Disney movie I like is Shrek,Swan Princess, and Anastasia otherwise than that im a Disney fan for life even though im not a little girl anyone but I don’t care I love them so darn much.
I absolutelly LOVE Disney, but I like Pixar too; all Pixar films are great! But I love Disney more, because I grew up with these movies (not that I like every Disney film...).
I'm not really interested in Dreamworks- I don't think their movies have the warmth that the Disney/Pixar ones have.
