Brave, Inside Out and Toy Story 3 are my favourites. So is Monsters Inc. and The Incredibles.
I also like the first 2 Toy Story's, A Bug's Life, Ratatouille, UP, the first Cars, Monsters University and Finding Nemo.
By the way Chat, Big Hero 6, Frozen and Wreck-It Ralph aren't PIXAR, they're Disney :) xx
