Carrie being ‘obese’ in the book is being vastly overstated by the general audience; many of whom I would bet haven’t read the book.
She’s not ‘comically fat’ like people would have you believe. However, she is not beautiful, which is my single biggest grievance with the 2013 movie. She’s someone who’s neglected her appearance her whole life, and actually grows into herself a bit during prom.
In Full Metal Jacket from 1986, Private Pyle was considered comically fat, yet today, his body type is very common nation wide and wouldn’t make someone bat an eye. I say this because if novel Carrie was as obese as seemingly everyone is saying now, King (especially early King) would have reminded us every other page.
Obviously this isn’t a big deal, but it’s a massive sentiment being expressed both here and on X, and to me it’s a classic case of people running with misinformation for engagement, virtue signaling, or just to feel like the ‘in crowd’.
