Inside Out is probably the biggest gamble that Pixar ever made trying to tell an animated story. It's more geared to adults than any other film they have ever made. It's complicated, with a lot of very complex metaphors. It attempts to tell a story far more related to the real world than any they have ever told as far as I can tell. There's no witches, magic, space-rangers, talking inanimate objects, or the like. And yet.
