Hank Perlman’s new Kraft Mac & Cheese spots are making headlines all over the place. First AdWeek takes a look at the new health-conscious aspects of the campaign while Creativity Online focuses more on the humor in Estelle Harris’ spot (we have a feeling someone’s a Seinfeld fan over at Creativity). If you’d rather split the difference and hear about both the health and the ex-Costanzas you can go on over to Little Black Book where they’re just loving the campaign for what it is: pure fun.
