I believe that 99 percent of successful TV shows change an immense amount from the pilot to the tenth or twelfth episode.
I hate shows, personally, where people stand around tossing stuff at each other, and any character can say any line, because you don't believe any of these characters care for each other. I used to fight with my friends who wrote on 'Seinfeld,' because they had such great pride in saying it was a show about nothing.
I like the end of the year to be about something. Especially with younger shows, the network pushes you to make self-contained episodes; they don't like them to be serialized: 'We want this one to be funny for someone who's never watched it and will never watch again.' And I go 'Why would anyone want to do it like that?'
