I love Megan Kearney's impressively concise summary of the history of the relationship development between Beauty and the Beast over time! Read her whole reply here, summary below:
"So, in trying to sum up, traditionally Beauty and the Beast has been a story about a young woman’s journey to accepting an unconventional male partner. In the twentieth century, it become a popular metaphor for the awakening of female sexuality and power. Now, more and more, we see it as a metaphor for the channeling of negative masculinity into positive masculinity. The story evolves. We pull new meaning from it, stretch it this way and that, examine it in the mirror, and take it apart to see how it ticks. It changes to suit our cultural needs, and it will continue to change."
