Will have spoilers below!
Have loved GA since it was first broadcast although don't think it's anywhere near as good as it used to be, so have been re-watching since the start.
I now can pinpoint its demise - season 6!
Starts with George's funeral, then the merger with the horrible people from Mercy West, Izzy leaving, the Chief drinking, Teddy arriving and all the angst with the Owen & Teddy! Too much change and too many new characters in a short period!
Before this, it was practically perfect & then season 6 onward is downhill all the way (with a few amazing bursts - the shooting episode; the musical episode - can't remember others right now but no doubt there will have been a few more to keep me watching).
Anyone else agree or think otherwise?
