Well, considering I am not the target audience of these ads I am not sure my words count (in the words of Rachel Green in the sitcom Friends "no uterus, no opinion"). Still, apparently these two films did make a splash online (you can watch them here and here). Obviously Sanita (the maker of Private) goes directly to the main idea - how soft, flexible, innovative, comfortable, and protective Private (or rather the new Private) is). It shows it by using cotton, feathers, tulle fabric and ballerinas. In the second film it shows a cocoon that becomes a butterfly and then cut to the ballerina doing a pointe. All colors are pseudo-blurry very feminine (duh!) quite cosy and dreamy (do note, Private is a brand of sanitary pads so periods for women can be difficult, tiring, hard, and very painful so the suggestiveness of Private is done on purpose).
As I said, I am not targeted by the ads but from what I understood it's that women online and social apps were actually chatting about them. Also there is a hashtage #the_private_revolution to go with the new iteration of the product.
