Exactly. for instance If they hire an actor who is not right for a particular role, they are unable to quickly change (as in years back when they had someone recast for the role of billie, or Jennifer, and were able to change the actor after just a couple dozen appearances. Or a story, that may have sounded good on paper, or a fabulous idea for shock value, boost ratings, etc. Such was James Reilly's idea to kill off a whole slew of MAJOR characters. He got told, in no uncertain terms, Fix this, we don't care how, but fix it! (This is what led to Melaswen, and an entire town having been hynotized or some such, into believing it all really had happened).
The present writing team had a lot to "clean up" when they came aboard, in addition to doing the 50th, so their work was cut out. My personal opinion is that, while initially, the co-headwriters were on the same page as to what they had to do, and wanted for the future, they eventually were not in agreement as to the "how". So, the difference began to show, one took a leave of absence, Sony pulled in a writer from another soap.....(we have yet to see the result of that, although it happened months ago).
NBC is going to have to make some concessions, is my guess here. But.....we will just have to wait and see.
