I agree with most of the other comments. The show seems rigged towards the titans. On numerous occasions the titans dish will receive more criticism than the guest chef but they miraculously get a higher score.
After the 1st round when the judge knows who is cooking, almost certainly the judge knows who cooked what dish even though it is a “blind tasting”. It would help if there was more than one judge or if the chefs were not revealed to the judge until the end of the 3rd round.
