I like Masterchef. I have seen different seasons and different international editions (US, Canada, Spain, Argentina, Paraguay) and you notice some similarities between them.
In the kids' shows the producers do not try to create fake rivalries like they do in the adults' episodes.
In all programs you can see how some of the contestants are shown to be favorites, and they have a lot of camera time, just to suddenly being dropped just for a bad dish. And you see how some contestants keep going and going even if they don't seem to to really well.
