It was nostalgic and I loved the Barbie Dream world but the plot was weak. Little girls like to play with Barbie because they like to dream or fantasize and no little girl dreams of becoming ordinary when she grows up.
In addition the movie male bashes and degrades men. I felt sorry for Ryan Gosling that he was in it. It’s like Hollywood has decided that we all should be single and alone as women.
It’s just not how humans were made.
