After > 30 series, I've finally stopped watching

It has been going downhill for such a long time, but the last few episodes I watched were just so bad, I can't watch any more. Duffy coming back, I think is a mistake. She surely wouldn't come back as a Sister after being out of emergency medicine for so long (she been a midwife). That isn't why, though her poor acting hasn't helped. And talking about poor acting, Robin has just never improved since she arrived. I just don't believe in her as a nurse. Some of the acting is good, nice and natural ( Max, Dylan, Cal, even Ethan), but they just highlight the bad actors.
The storylines are old and tired, and oh so predictable. And you can spot the actors who have been in it playing several different parts.
The crash with Grace and Connie was too unbelievable. Maybe I could believe ONE of them might survive, but BOTH? Really?
So adieu, Holby City Hospital. You inspired me to become a nurse, but now, I must leave you. Maybe I'll be back one day...
