Your argument is purely semantic and not really substantive unless you define what a “bad person” is. That’ll be different to everyone, so without a common operating definition of a “bad person” your point, while technically true, doesn’t really mean anything.
I find your criticism of the parts of the movie you don’t like to be super weak and unspecific. The crux of the entire movie is the juxtaposition between what’s it’s like in Barbie ruled barbie world vs ken ruled barbie world. It’s literally the lens though which the movie criticizes patriarchy.
Ken bringing patriarchy back to barbie world I don’t think was a twist, it was the clear narrative arc from the moment ken fell in love with patriarchy.
Matell being villains is a clear misreading of the plot from your point of view. Matell is the butt of the joke the entirety of the film. They don’t drive the plot, and were never in control of anything that happens. Why would you expect them to become the villains? That’s your own internal biases leaking (and maybe putting too much of Mugatu onto will Farrell)
Lastly, in much the same way that the opening of barbie is an homage to 2001 a space Odyssey, (that scene they are parodying specifically in the original movie is about the death of old paradigms and the beginning of new ones), the beach battle is an homage to patriarchally driven war media, specifically D-Day scenes such as from saving private Ryan. It’s the death of patriarchy subverted through a traditionally patriarchal approach.
You’re right. There’s zero Jewish representation in the Arab world while Arabs make up about 20% of the Israeli population (and hold positions of power within the country). Israel is a tolerant society while saud, Qatar, etc. are largely intolerant of Jewish existence (they genocided their own Jewish populations).
