Best: 1 – Pinocchio (1940)
Rotten Tomatoes Score: 100%
This might require a bit of an explanation.
Among film critics, Pinocchio has always ranked as Disney’s greatest animated film. Does it necessarily hold up to modern scrutiny? Not quite. But for an animated film released in 1940, it’s way beyond the competition. The animation in this movie is years ahead of its time, with wildly complicated techniques, to the point that modern animators looked back on this movie’s techniques to figure out how to make their own movies decades later.
I can think of other Disney movies I enjoy more from this time period (I LOVE Fantasia, holy s@#t I love that movie), but film critics over the years have always defaulted to this movie.
