Great re-positioning for Barbie. Instead of focusing on the stupid superficial stuff like looks, BBDO gets to the importance of play which is this: play unleashes our imagination. When we play, we imagine we can be anything. Also true when playing with Barbie.
Maybe you need to have a daughter to really get it, but unless you're one of those rabid no-fun types, I have to say, executionally, this spot is charming. The girl on the field actually said "Knees up like a unicorn." How could you not love that?
