I really think there are worse people in the soap than Stella, take Karl for instance, and NIck, talk about bad casting, only thing wrong with Stella was her script if they had give her a decent script, viewers would have forgive her foibles, but as she's had such a week part, how can viewers "warm" to her.
Her accent is not that bad, and i know lots of people who were born and bred in an area but don't necessarily have the local accent!
