I have very little use for the shows where it's just one cook inviting you into their kitchen to watch them make something.
I pretty much feel the same way, and that's probably why FN has gone the personality route - you're not watching brown butter ravioli being made by Giada Delaurentis, you're watching Giada Delaurentis make brown butter ravioli (complete with her fake-as-can-be Italian accent, which mysteriously comes and goes several times an episode), and there's a difference.
About the only one-cook show I like (love, really) is any one done with Jacques Pepin. Where other cooks making food do this:
"Ok, now I'm gonna add two tablespoons of butter to the pan and let that melt, and while that melts, I'm gonna chop an onion, and now I'm gonna add that to the pan, and now I'm gonna..." - it's all "I'm gonna this and I'm gonna that and I'm gonna this again." All they're doing is reading a recipe.
Pepin tells stories that relate to what he's cooking, and he weaves what he's doing into the narrative of the memory he's sharing:
"I love mushrooms. I like a lot in this, maybe a cup or even more. My mother, she would tell me, 'Jacques, stay out of the mushrooms!' but I never did, and one day..."
That's not easy to do naturally, and he excels at it. It's like he's telling a story while he happens to be cooking, and it's so pleasurable to listen to, I'll watch him make things I'd never cook or eat, just to be entertained.
