From 'Grey's' to 'Scandal': The Best & Worst Shonda Rhimes Characters
Worst: Izzie Stevens ("Grey's Anatomy")
Signature Shonda Quirk: Cancerous brain tumor and she was a teen mom.
Why We Hate Her: Two words: Ghost. Sex. It was quite possibly one of the worst things we've ever seen on television. Add to that the fact that she should have been fired a million times over, and not just because she tried to save her fiancé by cheating to get him moved up on the transplant list or because she started sleeping with her best friend to break up his marriage. There was also her careless mistake that killed a patient, followed by her blaming her husband for her much-deserved firing instead of recognizing her own incompetence.
