Our family enjoyed watching both shows. My DW wish the Master Chef Junior will inspire our DDs to cook. So far, except from occasional baking pastries/cookies, bake potatoes, fried eggs, and mac n cheese, they are not interested.

Child Genius is sort of different. It doesn't inspire us. Instead, it give us, the parents, what to avoid. My DDs like to critic the parenting styles of the participants. And they sympathize the kids on the show and we have been following the show.
