Young girls are oversexualized really early. I did not watch Cuties and I might watch it based on what you wrote. I am not the type that dislikes spoilers. I feel that if a story is worth seeing, then me hearing elements of it won't ruin it for me.
I agree with you that film sometimes uses overexaggeration as a powerful element to bring attention to an uncomfortable issue for the audience. Thanks so much for writing about the film and also bringing attention to the issues that are underlying in it.
