I knew nothing about the movie when i watched it and even i knew or highly assumed that everything in the movie is a real barbie thing, so i didn't see the point of one of the main character pointing it out. It just felt off to me. Kinda like: don't blame us, the movie makers, it was a real thing. And i nean that specifically, not the part where they freeze framed the clothes and accessories and named them.
Like i found the barbie living in the tree house hilarious, but thanks for letting me know that it's a real thing that you could buy, and thank god that lady knew everything and anything about barbies to tell us.
Maybe it would be funnier if the Mattel guys were barbie nerds who would point out stuff like that. Idk, it didn't make the movie bad or worse, it just feels dumbed down, for no reason.
