Masterchef UK and Masterchef: The Professionals are both stellar shows. Love the emphasis on cooking, love the seriousness of the amateurs, and love the challenges (mystery box, skills test, invention test, etc.). Masterchef USA is nothing like the original format. In general, the US-based shows all have too much emphasis on the competitive aspect of the show (earning ways to screw everyone else, lots of contestant conflict) whereas the original UK shows focus on the food. The contestants rarely have a bad word for each other, and there's none of the "twists" which so often cause conflict and backstabbing. Basically, the UK food shows almost universally beat the US versions. And I say this as a Canadian.
