She needs to embrace what she's good at...
What is frustrating about her career is she seems stubborn in not doing what she was loved for. HORROR. It is crazy and makes 0 sense that her last horror role was in 2008 (and it was awful). Ringer was awful (and cheap, lacklustre etc.) and Crazy Ones was weak as hell (Sarah isn't really that funny, she is sassy but she needs balance with more serious moments).
A whole generation relate Sarah to horror movies, she is a cult icon that could easily be staring in bigger better projects. There have been countless rumours that Ryan Murphy offered her a role in one of the earlier seasons of American Horror Story. Why would she not take it?
Now there's plenty of new Horror styled TV shows out there or in the works (Scream Queens, The Strain, Scream, Stranger Things, The Exorcist etc.) Fact is, they would jump at the chance of getting Sarah as she does create a bit of media hype - especially if they poked fun at her previous roles.
I honestly don't know how you have Neve Campbell (who has similar acting talents to SMG) appearing on House of Cards but Sarah can't get a hit.
Her agent is awful. Sarah could really be high level if she tried, but she needs a major revamp. Look at Marc Jacobs campaigns they have Bette Midler, Cher, Winona Ryder, Christina Ricci, Missy Elliot, Sissy Spacek etc. These are all women who may not be relevant anymore but have created a legacy and are pop culture icons in their own right (I am not saying SMG is as big as Cher etc. but you get the picture).
Look at Ryan Murphy's next project 'One Hit Wonder' about three fallen pop stars from the '90s form a super group to re-ignite their careers. It has Paltrow already confirmed (she's a sub par actress and is generally disliked by the public) why isn't SMG going after these kind of gigs?
Sort your *beep* out hun before its too late.
