This Movie Wasted An Opportunity With Gaston
The prince started out spoiled, selfish, and unkind. Thus, the Enchantress transformed him into a Beast.
In the opening music number, we are introduced to a character who paralleled the prince in being spoiled, selfish, and unkind. That character is Gaston.
The story was centered around a redemption arc for the prince who was turned into a Beast while at the same time showing us how similar Gaston was to the prince before the Enchantress showed and how much worse the prince could have turned out.
Sadly, it doesn't come full circle. The whole opening prologue could have been a chance for foreshadowing for Gaston's fate as well. Not only is Gaston conceited and cruel to others, but he is blessed with popularity, strength, and many impressive skills. The climax and Gaston's defeat could have involved the Enchantress making another appearance and cursing Gaston, taking all of those things away from him and giving him the same chance to learn the error of his ways and earn his body form back like she did with the prince.
Instead, Disney opted for the cliche "villain dies from falling off a cliff" trope with Gaston.
Beauty and the Beast is still one of the greatest Disney movies of all time, but how much more would it have stood out if Disney had followed through better on its foreshadowing and theme of redemption as well as at least tried to be more original when it came the fate of the antagonist?
