While I think Suki is okay, perhaps it is time for change there too. I will say though, that Kori seems so dry that I don't think he would have been any better with a different co-anchor.
This show was in it's heyday when Craig Treadway & Tiffany McElroy anchored 5am-7am, and John Muller and Lynne White anchored 7am-9am, with Linda Church on weather, Emily Frances on entertainment, Larry Hoff on features, Jill Nicolini (and before Marysol Castro) in Air11. Once Lynne left, it was the beginning of the downward spiral.
Their current graphics package sucks. The blue and orange don't really scream news, and the graphics are too bulky. Tamsen needs to go at 10. Bring in a Jackie Hyland or Cathy Hobbs or even Jodi Applegate to anchor at night if they don't want to revert to Kaity.
