Are they though? Or are the channels just trying to cover their backs? Anyway it's one thing to put a warning before an episode saying there are scenes of miscarriage, violence whatever. It's another to give details of the whole storyline weeks before.
I swear they have them before every episode now regardless of what's in it! There's always a warning of strong language or upsetting scenes and then literally nothing happens
I for one would appreciate a warning about all the scenes of people throwing up that producers love to stick in while I'm eating my tea!
