10 TV Shows That Went Way Too Far

10. Izzie's Ghostly Grief - Grey's Anatomy

Grey's Anatomy has a long history of slightly odd storylines, mainly where its unlikely medical cases are concerned (remember the guy who ate dolls?), but the series was never stranger than when surgical resident Izzie Stevens (Katherine Heigl) started hallucinating and even sleeping with the ghost of her late ex, Denny (Jeffrey Dean Morgan).

Now, this subplot as a whole isn't as bad as you might remember, serving as a powerful if jarring exploration of grief and mourning since Izzie blames herself for Denny's death and is seeing him because of the cancer she's yet to be diagnosed with, but the length of it and its unsettling intimacy is far too odd to be as moving as it wants to be. 

Credit should go to Heigl and Morgan for giving such a mismatched storyline the depth they did, but Grey's Anatomy fans the world over will all likely agree this reunion never should have happened. But hey, when a series has run for as long as this cult favourite has, you're bound to have some duds.
