Reality TV just got a whole lot younger — thanks to children chopping broccoli! They’re doing battle on Fox’s MasterChef Junior, a cooking-competition show that offers no end of potential hazards for little ‘uns, and we don’t even mean host Gordon Ramsay’s (toned-down) signature criticism. High shelves with giant KitchenAid mixers! Heavy pans filled with hot oil! It’s enough to make you worry for those crafty tykes’ safety — and to dose you with a soupçon of déja vù. The last time reality-show producers threw a bunch of children in front of the cameras and left them to fend for themselves, the result was Kid Nation, the short-lived, controversial, but nonetheless beloved 2007 CBS competition program that rewarded its tiny participants with gold stars and punished them with a bottle of unmarked bleach and bullying. So how closely do these two flyweight contenders match up? Let’s check out the tale of tape.
