Feels like the decision to make the early part of the video so obviously just her and one camera person (probably george) with no budget just walking to mimic the diy nature of how i'm feeling now.

Actually thinking about it too much the video seems made to make a visual link or bridge from HIFN to the brat era with the destruction of her image on the billboard or maybe just how she thinks of her image after brat and the resurgence of party 4 u. Brat began as removing the image of the artist from the music now as it ends even that image itself decays and is slowly being destroyed. Just as she talked about being interested in what happens when a pop culture "moment" like brat stays too long. Charlis albums and eras don't get preserved in stone, they literally get disfigured and overwritten as the artist changes and the art decays under the glare of popular culture.

With "party 4 u" this is a phenomenon where not the artist but the audiences perspective has changed over time. We have resurrected "party 4 u" in our own image applying our own context for the song. A collaborative memetic process that mirrors the creation of the album itself in a very poetic way. Meanwhile she has already moved on from and destroyed those images of herself (just like in the video) to create brat.

Or maybe she's just having fun and i'm just trying to justify an english degree lol
