I love classic Disney 2D animation, and this one fits right up there with some of the best.
Sometimes the villains in Disney movies are a little too evil (Huntchback of Notre Dame, and Tangled) because they're truly evil to the core, and this one falls in that category.
The alligator is almost a carbon copy of the singing alligator in All Dogs Go To Heaven. That bugged me.
It felt a little long, and my kids have no desire to see it again, but I enjoyed it otherwise.
