Since 1995, Pixar have been pretty much the undisputed champions of Western animation, and it isn't difficult to see why. While their biggest competitors were making entertaining but ultimately childish films for younger audiences, Pixar have been creating mature films with interesting concepts, engaging characters, robust narratives and increasingly intelligent themes, all while still managing to appeal to audiences of all ages.
But the gap between Pixar and its rivals has been closing for some time, and Zootropolis (or Zootopia as it is called elsewhere) is a great example of a non-Pixar film that manages to reach the same heights that Pixar have been reaching fairly consistently for the last two decades. It isn't quite there, and at times you can definitely tell that it is a Disney film rather than a Pixar film - but for the most part, you'd be forgiven for thinking that the distinction is ceasing to matter.
