Do you honestly think Kathleen Kennedy knows less about making movies than the guys who made 21 Jumpstreet and Cloudy With a Chance of Meatballs?
22 Jump Street and The Lego Movie, too; all of which were very successful, so I guess I fail to see your point.
The point is Kathleen Kennedy has worked on more movie productions as well as having greater success. Perhaps she knows something about movies after all of her experience.
