I stopped watching Grey's Anatomy two seasons ago; it got a little too soap opera like for me. I watch medical shows for the medical stuff not for the personal drama. I've heard Grey's has dead people walking now and affairs right and left. So be it. They have a huge audience and I don't begrudge them.
I see now that the character George is leaving the show. T.R. Knight is not happy with the management and he feels his character isn't going in the direction he wants. Fine with me. Apparently fine with the producers too.
If you view T.R. Knight's career information, you'll see he really didn't have a career until he was on Grey's Anatomy. I think perhaps he should have considered that people love the character George and not necessarily T.R. Knight. It might have been smarter to get some other work during hiatus, ala Katherine Heigl and test his staying power before quitting.
I wish him well. I loved George. I hope I love T.R. Knight too. We'll see.
