Like with Desperate Housewives, the show has reached an expiration date. I was a die hard fan of Greys Anatomy the first 3 seasons, and then gradually lost interest episode by episode. The new characters are not very good. The people who were there from the beginning is losing their touch and becoming more and more unrootable, spoiled and whiney. At this point the only character that still feels fresh and maturing is Callie. Even Cristina has lost her spark, which is unforgivable by the writers. And don't get me started on Meredith. She just gets more childrish and unbareable by the season. And what has happened to Dr. Bailey?
Greys should do a Desperate Housewives and call it quits while still having some dignity left.
