What a let-down!
This is my opinion: Somewhere along the line, they decided they just like Aaron. And almost every week, he screws up (except for the week with the RR Yummo thing). But they like him, so they make excuses for him over and over.
So this week, he got the easy promo. His 3 minute performance totally tanked, and his food was week. But they just couldn't let him go. They are in such a dillema, because they just want to give a show to this guy, but he consistently doesn't live up to their expectations.
They should have let him go.
Their original problem was the casting, and now they are in a bind.
* Adam can only cook one kind of food and knows nothing about anything else. He does his own food well. But his own food isn't so original on the Food Network.
* They just don't like Lisa, and they think no one else will either. She is the most talented chef they have of the three remaining. She knows food, and her food is classy and the kind of food that makes a person feel special.
* Aaron: first he had no presense on camera. That lasted through most of the episodes, but someone else always did worse, so he remained. In Vegas, he did a good promo, but for the rest of the time he had no presense. He did a bunch of pasta dishes. No one was impressed except for the crabcake. They clearly should have said goodbye.
