[Scarlett.]

Anita Turner - Nearly destroyed Emmerdale, brought in stories like Doug getting crabs - done for ****s and giggles, though thats probably the main factor that lead to the whole production team being replaced

Susan Bowers - I dont watch Neighbours, but apparently she's fooked up the show, and fans are waiting for her to be axed

Kim Crowther - Responsible for Corrie's current lull, last episode tonight, she had a knack for bigging up storylines, then failing with the climax...also she had trouble keeping spoilers in!

Louise Berridge - Responsible for EE's big lull throughout the 2000's, until Deidrick Santer turned up and made the show good

Kathrine Beedles - Not as bad as Anita Turner, her early reign was good, though she did seem to have an obsession with blowing **** up!

EDIT:

Lucy Allen - Similar to Anita Turner, she nearly destroyed Hollyoaks, but hats off to Paul, the show is improving
