Yup. I saw it, and I really enjoyed it. All top notch acting. Great, characterful, special effects. And the writers knew exactly when to hand wave details about the mechanics of how everything worked, to keep the story moving, without leaving the viewers hanging.
It was essentially a dark comedy about how it is complicated, confusing, and uncomfortable to be a human being. It's told through the lens of this intertwined Barbie-land set up, so the majority of it focuses on how it's complicated, confusing, and uncomfortable to be a woman; and part of the wrap up/solution at the end pulls in that it's just as complicated, confusing, and uncomfortable to be a guy.
It definitely earns its PG-13. While some kids movies have extra jokes that parents will get, but the kids wont; this movie is more like an adult movie filled with only jokes that kids won't get. There's nothing really there for anyone not at least in their teens.
