How would you rate or grade Tim O'Donnell's performance as executive producer/showrunner during the UPN seasons?

Amy Heckerling, who of course directed the Clueless motion picture, was the EP/showrunner for the first season on ABC. When Clueless was cancelled, and picked up by UPN, Tim O'Donnell took over. If you want to get technical, Amy Heckerling said that after the first six episodes, she was gone.

O'Donnell said that the show would focus more on the five central teenagers than did the ABC version. He added he was more interested in watching things that happen in school because the interesting stories happen there.
