I enjoy watching emeril from time to time, but his act can and does get tiresome. However, I have learned quite a bit from the show, and thats the point of it really.. After all, its not a show for chefs to watch... If the show isnt entertaining, people wont watch. Take bobby flay's shows..... yawn.
There just aren't that many people on tv that can make people stay tuned for the duration while cooking what could be an otherwise boring pizza, salmon, baked lamb, or whatever, dish. And I bet he's got more dough in his wallet than we have in our kitchen :) So that means the formula, however boring to you, is working for him, and the millions that tune in.
Just my humble opinion.
