I never understood y'alls hate for Dawn. Maybe I was watching a different show. She did kind of screw Sarah on the Restaurant Wars, but it wasn't on purpose and she admitted the next week that she should have handled things differently. Beyond that, she seemed to be intense, but well liked by everyone around her. Her inability to plate was frustrating. I did read an interview with Tom and he said that contestants miss items on plates all the time. The issue is, all of the guests this season were the ones being filmed, so it seemed like a much bigger issue than it normally is.
As far as her abilities, I don't think she was that far behind Gabe and Shota at all. In the elimination challenges (before the finale), this is how it looked (Win/Otherwise Top/Bottom):
Gabe: 3/3/2
Shota: 4/5/1
Dawn: 1/6/2
She also won 3 QF, compared to 1 for Shota and 1 for Gabe. Overall, before the finale, she performed below Shota but about the same as Gabe, and maybe better if you include QF.
Anyway, I was rooting for Gabe (before the AAS story this morning), but would have been fine with Shota or Dawn. I thought it was a really fun season overall, especially considering the limitations due to COVID. I liked having the old contestants back to judge and I'm not sure you can do that in normal times.
