Remember when the characters had problems that didn't solely revolve around having an addiction, battling depression and/or PTSD? When everything wasn't an after school special/social justice topic?
Oh right, that's when the writing, the acting, and the characters were good.
Richard's an alcoholic, Amelia is an addict, Owen has PTSD, apparently now Jo is depressed... I'm tired.
Not to mention how all Grey's/Krista is doing now is writing for plot and making the characters fit around that, as opposed to writing for and staying true to the characters.
This is what happens when you value money over storytelling. So what if Grey's remains ABC's highest rated show and broke the record for "longest primetime medical drama" if the stories and characters are suffering because of it.
