These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Jerkass Woobie: Darla, if you stop and think about it. The Woobie part isn't really touched upon, as she's the Big Bad, but she's a young child who is in the spotlight pretty much twenty-four seven, has no parents to speak of and at the end of the film becomes a washed-up janitor. Sure, she deserved it, but she didn't become an Enfant Terrible by herself.
What Do You Mean, It's Not Political?: There's plenty of comparisons someone can draw watching this movie to the plight of minority representation in film as represented by the animals. Considering it's in the golden age of all times could only strengthen this view since it took decades for non-white actors to reach prominence.
