As a folklore fan, the villains of Wendell & Wild resembling "dragons hoarding gold in their stronghold" is no accident.
When you look closely, most early folk stories and fairy tales were "oral traditions," or word-of-mouth stories told by illiterate peasants who were trampled by their literal feudal lords. (Landlords, landladies, barons, dukes, etc.)
The common folk figure (pre-Victorian Era) of "dragons hoarding their gold in their stronghold" and "ogres living in castles" like in The Hobbit and Puss in Boots were a way for peasants and commoners to air their grievances about their feudal lords without getting in trouble. A.K.A. "OH, I'm not mad at my [rich, white, Christian] feudal lord. This story is about a DRAGON / OGRE, not a regular human."
And I love how Wendell & Wild captured that.
I love how Henry Selick and Jordan Peele exposed this.
The private prison / "for profit prison" assholes are thematically compared to dragons guarding their horde, just like the dragons and ogres of fairy tales, who were themselves based on feudal lords that peasants needed to gripe about in a socially acceptable way.
