They should have stuck with one storyline and not the 5 or 6 they tried to throw in. It would have been cool even to go with a version of what happens to Barbie in Barbieland when your brother steals your barbies to play with them. (Not in the movie btw) But get a moral of the story and stick with it. It was so incoherent. Best part of the movie was the "I am Kenough" shirt.
What made the movie watchable was the acting, costumes, and the sets (amazing!) The visuals were really on point. It really gets you excited just for the plot to let you down.
