He's by far the funnest chef to hate. Well, him and Emeril, blech!
Some site had a great line about Flay: "Never since Jamie Oliver has a face been more punchable..." or something along those lines. I don't actually want to punch Oliver, tho...
I'm shocked at how many people hate Molto Mario (Mario Batali) and the Barefoot Contessa! Mario does sound a bit condescending when he's explaining stuff to his guests, as does Juan Carlos Cruz (the calorie commando) but I've gotten used to his style. My beef with Mario (who is mighty knowledgeable, and who I think cooks real-time, like Rachel Ray, for the most part) is that he's always making icky stuff, like rabbit (yeah, I know there are bunny fans on this board. I et one myself in Berlin once...).
Sandra Lee is useless (she's the semi-homemade amazon)---she's a rib parboiler, for one! I loved Rachel Ray until my sister pointed out her non-stop chattering, and then she got on my nerves, but I'm back to liking her 30 minute meals (not so hot on $40/day and have never watched that celebrity show of hers, zzzzzzz). Sarah Moulton Howe doesn't have much ooomph to her, but her show is watchable as she usually has some great featured person or recipe, and she WAS after all an intern of Julia Child's back in the day. Love Tyler Florence (I hear he's genuinely nice) tho Jac (that blonde chick on How to Boil Water) is grating. I like Michael Chiarello's recipes, but he also has a sort of cold affect. Just not much oomph there either. I like George Stella (the low carb and loving it) guy and his family. And I like Martha Stewart (tho what do I do with my "Free Martha" shirts now?). And I love love love Raichlen.
