These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Master Chef
Creator's Pet: US Season 1 winner Whitney Miller has been accused of being this, as despite her constant, major screw-ups in the elimination challenges, the judges constantly talked about how awesome and amazing she was, and the only time she ever actually faced elimination was when the decision was out of their hands, and professional food critics were deciding on the bottom two for that challenge. Alejandra from Season 2 appeared to be going the same way, though her serving raw pork to the judges in her last episode was evidently too big a screw-up for her to recover from.
Elimination Houdini: Tali from the US season 3. He made only one dish the judges really liked, whereas the rest of his dishes have ranged from average to outright terrible, and he's been in the bottom two a total of three times. It's all made worse by the fact that he has quite a big ego, thinks his food is amazing and the judges just don't understand him. However, he finally got eliminated in the Top 9 (though he still talked of how the judges couldn't "see the genius").
David Martinez also from US season 3. So much so that when eight previously-eliminated contestants were competing to return to the competition, virtually all of them said that he did not deserve to still be in the running.
Max in US season 2.
Josh from US season 3 eventually became this after he was brought back, landing constantly in the bottom but still managing to stay.
Hate Dumb: It's generally not too good of an idea to get into an argument about which incarnation of the show is the best, especially if it's with a fan of the UK version (the original) or the Australian version (widely considered the hardest and most demanding).
For the American version, the fact that 3 winners have been attractive females seems to cause watchers to claim that the show is biased in favor of women.
